Tesla

• Vauban releases an electrically-charged grenade that adheres to any surface. On contact with an enemy, the grenade will deal 15 Blast damage. If an enemy approaches the grenade within 7 / 8 / 10 / 12 meters, the grenade will discharge. A single grenade holds a maximum of 5 / 6 / 7 / 10 charges, and each charge inflicts 80 / 100 / 120 / 150 Electricity damage. Charges are fired once every 3 seconds. Each grenade has a duration of 40 seconds; when a grenade uses a charge, its duration is paused for 0.75 seconds. The ability can be held for a short time and released, doubling damage and increasing status chance to 100%.
  • Arc damage and contact damage are affected by Ability Strength, and the contact damage can be increased by body-part multipliers.
  • The arc damage has a low status chance. An Electricity proc will chain 50% of the initial damage to surrounding enemies in a small area of effect while briefly stunning the initial target.
  • For more information about the contact damage, see this blog and this follow-up.
  • Each grenade can deal a total of 400 / 600 / 840 / 1500 damage. Sticking a grenade directly on an enemy can potentially deal that entire amount to the enemy for its duration.
  • Blast damage is effective against Machinery and Fossilized, but less effective against Ferrite Armor and Infested Sinew.
  • Blast status effect forces all enemies within a 5 meter radius to stumble and fall.
  • Electricity damage is effective against Machinery and Robotics but less effective against Alloy Armor.
  • Electricity status effect chains 50% of Tesla's base damage to surrounding enemies in a small area of effect. Shocked enemies will also be briefly stunned.
  • Number of charges is affected by Ability Duration, while the grenade duration is not.
    • Because of this, the maximum number of usable charges is capped at 18.
  • A grenade can only target one enemy at a time, expending a single charge per attack.
  • Attack range is affected by Ability Range.
  • Grenades can only attack enemies in line of sight (cannot shoot through walls or corners).
• When the ability is charged, damage is doubled and status chance increases to 100%. Both the uncharged 10% status and charged 100% status are unaffected by mods.
  • Damage is further increased by 25% when a charged Tesla shocks an enemy under various forms of immobilizing crowd control, such as Bastille or Vortex.
• Does not attack the Stalker.
• Can be used while performing many actions without interrupting them, including reloading.
• Can be cast multiple times while active.

Main article: Tesla Link

Tesla Link is a Warframe Augment Mod for Vauban that makes each pair of Tesla balls form energy links between each other that deal Slash damage upon contact.

• Place on allies such as hostages, fellow Warframes, or even sentinels to create a sort of melee protection sphere. Best used on Rhino/Excalibur Warframe with their Rhino Charge/Slash Dash ability.
• Placing several Tesla in exactly the same spot will result in the charges being released at nearly the same time, and placing them in a line will result in each firing one at a time as an enemy approaches, dealing more constant damage.
• Placing several Tesla on a rotating body allows the Teslas to possibly "orbit" into range of an enemy, and giving them all a chance to fire at said enemy. This effectively increases the range and increases the Tesla group's overall rate of fire.
• Works best against Corpus and less effective against other factions, while still acting as a moderate damage tool.
  • Electrical damage deals normal damage to shields, and only deals extra damage to unshielded MOAs, so it is realistically best for Infested.
  • Grineer armor will reduce the damage dealt considerably.

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 number of charges to 30 theoretically, which caps at up to 18 practically due to the grenade duration.
  • Reduces range to 4.08 meters.
• Maximized Ability Efficiency reduces cost to 6.25 energy.
  • Reduces number of charges to 4
• Maximized Ability Range increases range to 33.6 meters.
  • Reduces arc damage to 60 per charge and contact damage to 6.
• Maximized Ability Strength increases arc damage to 618 per charge and contact damage to 61.8.
  • Without  Energy Conversion and  Growing Power, increases arc damage to 505.5 per charge and contact damage to 50.55.
  • Increases cost to 38.75 energy.
  • Reduces number of charges to 7

• Even after the Update 23.3 rework, the maximum allotted charges per grenade is still capped at 18 charges. Going over this by increasing duration further has no effect.
