Attributes

Each Warframe has a different style of play and a different set of stats and abilities that make them different from the other Warframes.

Power Mods
Warframes have abilities which can be affected by four types of modification: Power Duration, Power Efficiency, Power Range, and Power Strength. With the proper combination of mods and gear you can obtain a maximized value. See Power Mods and Abilities

Power Duration
These mods affect how long a Warframe ability lasts. A great frame for maxing duration is the Vauban with his Vortex skill. The reduction in range does not affect the Vortex and is sometimes prefered for the Bastille  for when doing Infested defense missions, since they will be easier to hit more of with a launcher type weapon.

Mods that affect Power Duration positively:

Maximized at +157% with a negative effect of -66% range.

Power Efficiency
These mods affects how much a Warframe ability costs to cast. See Power Efficiency (Mechanic) for a detailed explanation of the mechanics. Power Efficiency has a hard cap of 75%: an ability which costs 100 energy cannot be reduced below 25 energy.

Mods that affect Power Efficiency positively:

Maximized at +90% with a negative effect of -60% duration. With the hard cap at 75% it is recommended to not completely level Fleeting Expertise unless utilizing Blind Rage in the same build.

Power Range
These mods affect the radius and targeting range of Warframe abilities.

Mods that affect Power Range positively:

Maximized at +135% with a negative effect of -60% Power Strength

Power Strength
These mods affect the damage and the 'potency' of Warframe abilities (such as the number of shadows summoned with Nekros' Shadows Of The Dead, damage multiplier of Banshee's Sonar and Energy cap on Trinity's Energy Vampire).

Mods that affect Power Strength positively:

Maximized at +184% with a negative effect of -55% Power Efficiency and -27.5 Power Duration. Maximizing together with a maxed Fleeting Expertise on a frame that doesn't use duration is a good tactic, since it will more than double the damage of your skills and also make it 5% cheaper to cast (the downside of this tactic is that it requires 4 mod slots in your frame, and takes a lot of resources to max the mods).

Stamina
Stamina is a resource that is self charging and able to be depleted, which is used to sprint, melee, wall run and block. It is shown in the top right warframe conditions info box as a green bar under the blue energy bar. Melee, sprinting, wall running and blocking will exhaust a player's stamina in seconds upon performing the action. When a player is not using any of the stamina dependent maneuvers, the stamina will recharge at a fast rate. It is possible to increase a frame's maximum stamina and the stamina recharge rate with stamina-based mods like Quick Rest or Marathon. The melee mod Second Wind can provide boosts of stamina upon killing enemies with your melee weapon, making hit-and-run combat more viable as melee drains stamina quickly.

All Warframes have a base stamina count of 80 except Valkyr and Hydroid, who have 150. Level has no effect on stamina.

Stamina orbs are available for pickup only in the Clan Dojo's Obstacle Course.

Mods that affect Stamina positively:
