Mesa

• Mesa converts 40% / 50% / 60% / 70% of the total damage inflicted by her primary and secondary weapons into raw energy. A maximum of 20 / 50 / 90 / 140 damage is stored for every instance of damage, and a maximum of 400 / 800 / 1200 / 1600 damage is stored at full capacity. When Ballistic Battery is deactivated by pressing the ability key again (default 1 ), the stored damage is unleashed on the next gunshot fired.
  • Charged shots from Gunblades will also contribute to Ballistic Battery's damage.
  • Damage percentage and maximum stored damage at full capacity are affected by Ability Strength.
  • While active, a charge counter becomes visible on the ability icon that tracks stored damage from 0% to 100%.
  • Instances of damage that contribute to the charge counter include Multishots, Critical Damage, DoTs, Status Effect damage, and Syndicate Radial Effects from Weapon Augment Mods and Syndicate weapons. For example, Ballistic Battery will store damage from Torid clouds as well as damage from the physical projectile.
  • Once deactivated, the stored damage is added to your equipped weapon's damage. The stored damage will have the same damage composition as the equipped weapon and is not affected by base damage mods (e.g., a Lanka with a maxed Serration equipped will inflict 300 × (1 + 1.65) + 1600 = 2,395 Electricity damage from a fully charged shot when Ballistic Battery is deactivated).
  • Elemental Damage Mods, Faction Damage Mods, Critical Damage, Headshots, and Status Effect damage will factor in the increased damage in their calculations.
  • The stored damage is only applied to a weapon's projectile damage in most cases. This includes the Torid, Penta, and Ogris. Syndicate Radial Effects, while able to contribute to the charge counter, are not affected by the stored damage upon Ballistic Battery's deactivation.
  • Stored damage is not split across multiple projectiles in the case of multishot weapons; only a single projectile can acquire stored damage.
  • Beam Weapons get the bonus damage applied to the whole magazine as long as you do not lose your target.
• Does not affect melee attacks (including Redeemer shots).
• Peacemaker's Regulator pistols can contribute to the charge counter, and Ballistic Battery can be deactivated while Peacemaker is active. Stored damage can be applied to a single Regulator shot.
• Any effect which forcibly strips abilities - e.g. falling into a bottomless pit or entering a Nullifier field - will cause Ballistic Battery to discharge on the next shot, with the damage bonus intact, similar to when the ability is manually deactivated. Needs testing for the Stalker or for Zanuka's Dispel / Dispel Bomb.
• Mesa's body will glow in her chosen energy color with intensity and coverage scaling with damage stored.
• Has an initial cast of 0.5 seconds.

Main article: Ballistic Bullseye

Ballistic Bullseye is a Warframe Augment Mod for Mesa that gives shots enhanced by Ballistic Battery a chance to deal Status Effects.

• A simple-to-use but incredibly useful skill, make use of Ballistic Battery early and often. It can be extremely useful for eliminating heavy enemy units, as the skill damage value does not properly reflect the actual potential damage of a well-placed, fully-charged shot.
• The damage added is to your attack's base damage, so if you are using a weapon with a high critical chance/multiplier and/or aiming for a headshot, the added damage can turn out to be much more than 1600.
• Ballistic Battery stores energy when containers are shot, presumably because they use health to determine if enough damage has been dealt to open them.
• This ability can be used with a Furis pistol that has a Winds of Purity mod to easily restore Mesa to full health, should the shot connect.

Maximization is a form of specialization: mods may be blended to result in values that vary between the top-end limits listed here. Click any maximized link to learn how to build it.

• Maximized Ability Duration has no positive effects on this ability.
  • Has no negative effects on this ability.
• Maximized Ability Efficiency reduces cost to 6.25 energy.
  • Has no negative effects on this ability.
• Maximized Ability Range has no positive effects on this ability.
  • Reduces damage percentage to 28%, max damage per instance to 56 and maximum stored damage to 640.
• Maximized Ability Strength increases damage percentage to 288.4%, max damage per instance to 576.8 and maximum stored damage to 6592.
  • Without Energy Conversion and Growing Power, increases damage percentage to 235.9%, max damage per instance to 471.8 and maximum stored damage to 5392.
  • Increases cost to 38.75 energy.

• Rank 0 Ballistic Battery stores more damage per instance than other ranks.
• Ballistic Battery does not store damage dealt to the Eidolons' Synovia, it does however store the damage dealt to the Eidolon after all its Synovia have been destroyed.

• Mesa releases an energy lasso that swirls around her, causing her to gain 10% / 15% / 20% / 25% weapon damage. The lasso will remain active for 15 / 20 / 25 / 30 seconds.
  • Damage bonus is affected by Ability Strength. For example, +30% Ability Strength will increase the damage bonus to 0.25 × 1.3 = 32.5%.
  • Shooting Gallery grants an increase that's applied to your weapon's damage and stacks additively with other damage mods, e.g. Hornet Strike. For example, with +30% Ability Strength and a weapon that inflicts 250 base damage, regardless of the weapon's mods, Shooting Gallery will add (0.25 × (1 + 30÷100)) × 250 = 81.25 damage. Of that only (0.25 × (30÷100)) × 250 = 18.75 damage can be attributed to Ability Strength.
  • Duration is affected by Ability Duration.
• The lasso will lash out at 3 enemies within 10 / 12 / 14 / 16 meters with beams of energy every 1.5 seconds. Affected enemies will have their ranged weapons jammed and will stand in place and attempt to unjam the weapon over a short duration; melee fighters (for example most Infested, Butchers, or Prod Crewmen) will suffer a temporary stun instead.
  • Stun range is affected by Ability Range.
  • Can repeatedly affect enemies that recover from a previous weapon jam or stun.
  • Will prevent Volatile Runners from detonating.
  • For some reason, has no effect on flying enemies – Ospreys, Orokin Drones, etc.
• When playing in a group, two instances of the buff will spawn. One will stay on Mesa for the full duration of the ability, while another will periodically transfer between all allied players within an unrestricted range, temporarily providing the affected player with all benefits of the ability.
  • Duration per player is calculated by the following expression: Duration = Total Duration / (Total Number of Players - 1).
• Peacemaker and Operator Amps can be affected by Shooting Gallery's damage bonus.
• Cannot be recast while active.

Main article: Muzzle Flash

Muzzle Flash is a Warframe Augment Mod for Mesa, that makes Shooting Gallery emit a flash that blinds enemies before switching to another player.

• If this is the only ability you use there's questionable value in modding for Ability Strength as it will only add a trivial amount of damage, though this is more relevant when soloing as teammates will also gain damage.

• Maximized Ability Duration increases duration to 91.8 seconds.
  • Reduces range to 5.44 meters.
• Maximized Ability Efficiency reduces cost to 12.5 energy.
  • Reduces duration to 12 seconds.
• Maximized Ability Range increases range to 44.8 meters.
  • Reduces damage bonus to 10%.
• Maximized Ability Strength increases damage bonus to 103%.
  • Without Energy Conversion and Growing Power, increases damage bonus to 84.25%.
  • Increases cost to 77.5 energy.
  • Reduces duration to 21.75 seconds.

• Mesa envelops herself in an energy shield that reduces incoming damage from bullets and projectiles by 50% / 60% / 70% / 80% while reflecting the damage back to her attackers. The energy shield lasts 10 / 15 / 20 / 25 seconds.
  • Damage reduction is affected by Ability Strength and cannot exceed 95% under any circumstances.
  • Reflected damage is equivalent to what enemies would receive if they were to damage themselves.
  • Incoming hitscan and non-hitscan projectiles are physically redirected. As such, obstacles in the environment can prevent reflected damage from hitting enemies.
  • Reflected damage is not always directed to the source enemy; the damage can be redirected to other enemies depending on their position relative to Mesa and the source.
  • Status Effects are also reflected back towards enemies.
  • Duration is affected by Ability Duration.
• Projectile-based knockdown is resisted, such as the grappling hooks from Scorpions and Infested Ancients. However, knockdown caused by radial blasts from units such as Shockwave MOAs and Heavy Gunners will bypass Shatter Shield.
  • Bombard rockets will be reflected and often will ricochet back into enemies with a good chance of proccing blast, knocking them down.
• Cannot be recast while active.

Main article: Staggering Shield

Staggering Shield is a Warframe Augment Mod for Mesa that gives shots reflected by Shatter Shield a chance to stagger enemies.

• As damage reduction is capped to 95%, any Ability Strength beyond 119% will not have further effect to Shatter Shield. Maximum damage reduction can be achieved with just a rank 3 Intensify, or a rank 4 Augur Secrets for 3 less drain.
• Players should take caution, as while damage reduction will apply to Projectile/Hitscan weaponry, it does not apply to explosions.

Maximization is a form of specialization: mods may be blended to result in values that vary between the top-end limits listed here. Click any maximized link to learn how to build it.

• Maximized Ability Duration increases duration to 76.5 seconds.
  • Reduces reflect radius to 3.74 meters.
• Maximized Ability Efficiency reduces cost to 18.75 energy.
  • Reduces duration to 10 seconds.
• Maximized Ability Range increases reflect radius to 30.8 meters.
  • Reduces damage reduction to 32%.
• Maximized Ability Strength increases damage reduction to 95%.
  • Without Energy Conversion and Growing Power, the value does not change.
  • Increases cost to 116.25 energy.
  • Reduces duration to 10 seconds.

• Reflected damage from non-hitscan weapons is not calculated properly. The reflected damage enemies receive from non-hitscan weapons does not appear to factor in the enemy's level, causing the same damage to be reflected regardless of enemy difficulty.
• When shot by an Embolist with Shatter Shield active Mesa will receive the poison proc even if the damage source was friendly.

• Mesa stands her ground, holsters her current weapon, and draws her Regulator pistols. While Peacemaker is active, a focus ring appears in the form of a blurred reticle which can be aimed at enemies. Holding the fire button will cause Mesa to auto-target random enemies inside the focus ring up to 50 meters away. Each gunshot will reduce the size of the focus ring until its field of vision is reduced to 15°.
  • Maximum shooting distance is not affected by Ability Range.
  • The focus ring's field of vision resets to its initial value if Peacemaker expires or is deactivated.
  • In order to achieve target acquisition with Peacemaker, enemies have to be within range and positioned inside the focus ring, and Mesa must have line of sight with the enemy.
• Mesa's Regulator pistols inflict 50 damage per shot. This is not affected by Ability Strength, but is affected by secondary weapon mods and buffs.
  • Peacemaker has a built-in damage buff, increasing its base damage by 100% / 115% / 133% / 150%.
    • This buff is affected by Ability Strength and stacks additively with Damage mods, such as Hornet Strike.
    • For example, using maxed Intensify, Hornet Strike and Convulsion, a rank-3 Peacemaker will deal
      Base Damage × (1 + 1.5 × (1 + Strength Mods) + Damage Mods) × (1 + Elemental Mods) =
      50 × (1 + 1.5 × (1 + 0.3) + 2.2) × (1 + 0.9) = 489.25 damage.
  • All gunshots have a 300% critical damage multiplier with a 25% critical chance, a 10% status chance, and 100% accuracy.
  • Damage is divided into 50% Impact, 25% Puncture, and 25% Slash.
  • The mods that can be equipped on and affect Regulators include:
    • damage (e.g., Hornet Strike and Pistol Amp)
    • physical (e.g., Concussion Rounds)
    • elemental (e.g., Heated Charge)
    • multishot (e.g., Barrel Diffusion)
    • faction (e.g., Expel Grineer)
    • critical chance and damage (e.g., Pistol Gambit and Target Cracker)
    • status chance (e.g., Sure Shot and Pistol Pestilence)
    • fire rate (e.g., Gunslinger)
  • Regulators cannot be equipped with weapon augments (e.g., Winds of Purity), pistol range mods (e.g., Ruinous Extension), or Acolyte Mods (e.g., Sharpened Bullets).
  • Riven Mods are not generated for Regulators.
  • Regulators will still be affected by equipped mods in non-Secondary "Weapon-Specific" Sorties.
• Peacemaker is affected by and can trigger Warframe Arcanes.
• The pistols are fired in bursts of two gunshots.
• As Peacemaker is fired, it receives another damage bonus which increases up to a maximum of +150%.
  • The damage bonus is applied multiplicatively, independent of other modifiers.
  • Bonus does not stack with outside damage multipliers, such as Roar.
  • The damage bonus increases linearly with every burst, with the maximum amount being reached at the 20th burst.
  • This can be seen as an independent damage bonus of +7.5% per burst, resulting in
    Modded Damage × (1 + (2.5 - 1) ÷ 20 × #Burst).
  • For example, still using Intensify, Hornet Strike, and Convulsion on the 8th burst a Rank 3 Peacemaker will deal
    489.25 × (1 + (2.5 - 1) ÷ 20 × 8) = 782.8 damage.
  • Maximum damage bonus and damage bonus per burst are not affected by Ability Strength.
  • The damage bonus resets to its initial value if Peacemaker expires or is deactivated.
• The rate of fire will ramp up for each gunshot. The rate of fire will reset if the fire button is released or if no gunshots are fired during a brief period of inactivity.
  • The Regulators are automatic; players need only to hold down the fire button to continue firing.
• Peacemaker drains 15 energy per second and will remain active so long as Mesa has energy.
  • Peacemaker will end if Mesa runs out of energy or if deactivated by pressing the ability key again.
  • Activation energy cost is affected by Ability Efficiency, and the energy drain is affected by Ability Efficiency and Ability Duration.
  • Mesa does not benefit from energy recharges like Trinity's Energy Vampire, Rift Plane's energy regeneration, Zenurik's Energizing Dash, Energy Siphon, or Team Energy Restores while the ability is active, but she can benefit from  Arcane Energize, Rage's and Hunter Adrenaline's energy conversion, Orokin Void Death Orb energy restores, and Energy Orbs.
  • Peacemaker's energy drain is not converted into shields by Augur Mods.
  • Due to anti-AFK countermeasures, following two minutes of being immobile, energy gain from all sources will be stopped regardless of whether Mesa is scoring kills with Peacemaker.
• Casting speed (drawing the Regulators) is affected by Natural Talent and Speed Drift.
• The radius of the focus ring is affected by Ability Range, though the latter's effect is negligible.
  • The formula used to calculate the field of view angle with mods is non-linear and currently unknown.
• While Peacemaker is active, Ballistic Battery can be deactivated but not activated. Stored damage can be applied to a single Regulator shot.
• Shooting Gallery can increase Peacemaker's damage.
• After a very brief "draw" period, Mesa is completely immobile and vulnerable to damage while Peacemaker is active, although she will resist crowd-controlling status effects and knockdowns.
• Peacemaker cannot target Capture Targets or enemies inside a Nullifier Bubble.
  • Contrary to popular belief, Peacemaker can target the Stalker provided Mesa is playing in a Squad and is not the Stalker's main target.
• Peacemaker does not target invulnerable enemies.
• Peacemaker's shots can damage enemies across the Rift Plane.

Main article: Regulators

The Regulators are Mesa's signature Exalted Weapon, which are used when her Peacemaker ability is activated. Unlike other ranged weapons, the rapid-firing Regulators will automatically target and shoot at enemies within a large aiming circle directed by the player, removing the need for precise aim.

Main article: Mesa's Waltz

Mesa's Waltz is a Warframe Augment/Exilus mod usable in both PvE and PvP that allows Mesa to move at a reduced speed while channeling Peacemaker.

• Casting Shatter Shield before activating Peacemaker is recommended, due to Mesa becoming vulnerable to attacks while Peacemaker is active.
• While you cannot initiate movement while channeling Peacemaker, it can be cast while falling or immediately after initiating a bullet-jump, thus allowing you to start shooting before you actually arrive at your intended location. Channeling Peacemaker also makes you immune to the stagger effect you would normally recieve upon hitting the ground after a long fall.
• Limbo makes a great complement to Mesa when using this ability, as using Banish on Mesa allows her to become immune to enemy damage while also allowing her to damage enemies outside of the Rift Plane with her Peacemaker. If Cataclysm is cast anywhere with enemies inside Mesa may take damage if they fire at her, even she is not inside the Cataclysm but still under the effect of Banish.
  • While in the Rift Plane you should deactivate Peacemaker whenever possible to regain energy, especially in a group with multiple Energy Siphon Mods.
• Volt's Electric Shield will buff rounds of the Regulator's shots that pass through it.
  • Volt's Electric Shield will also cause the shots fired to have increased proc chance for Impact, Puncture, or Slash
    • Volt's Electric Shield has been noted to occasionally, unknown whether as a bug or not, cause a type of punch-through effect that will make Peacemaker penetrate targets. It has been additionally noted that the punch-through is not affected by peacemakers default range and can kill enemies hit by it, the highest example was roughly a kill 85 meters away from Mesa's default 50. Punch-through effect seems to hit once per 10 shots, so fairly often.
• Similar to most Warframe abilities, Peacemaker targets the enemy's torso to inflict damage. It is particularly effective against Corrupted Vor as all Regulator pistol shots will always hit Vor's energy core, the only body part where he is vulnerable to damage.
• Since Mesa stays immobile with Peacemaker active, it's highly suggested to bring a Sentinel with Vacuum equipped to pick up Energy Orbs and prolong the duration Peacemaker stays active.

• Maximized Ability Duration reduces channeling cost to 4.9 energy per second.
  • Reduces FoV to 8.88°.
• Maximized Ability Efficiency reduces activation cost to 6.25 energy and channeling cost to 3.75 energy per second.
  • Has no negative effects on this ability.
• Maximized Ability Range increases FoV to 24.15°.
  • Reduces damage bonus to 60%.
• Maximized Ability Strength increases damage bonus to 618%.
  • Without Energy Conversion and Growing Power, increases damage bonus to 505.5%.
  • Increases activation cost to 38.75 energy and channeling cost to 32.07 energy per second.

• Shots ignore, both friendly and hostile, snowglobes (Mesa can hit targets on the opposite side of a snowglobe whilst standing outside of it) and certain obstacles (such as Defense cryopods).
• Occasionally the draw animation for the Regulator pistols may not occur.
• Peacemaker's fire rate is severely hindered when the user's FPS is lower than 30, with lesser FPS resulting in lesser fire rate.
• Peacemaker can be utilized by Specters and still allow them to move to a certain degree of minimal slowdown.
• If the Warframe gets downed during Peacemaker, the primary weapon might be equipped instead of the usually available secondary one.
• When viewed in the Orbiter's Arsenal, the FoV angle is fixed at 15°, regardless of Mesa's range value. When viewed in a mission however, its value will be affected by Ability Range mods. It is currently unknown whether the angle's value is meant to be fixed at 15° or not.
