Can only be leveled past 5 with Banshee class mods.
Using any Moxxi weapons during "Fight For Your Life" time will not cause Immolate to activate. The reason is that Moxxi weapons will heal a downed character's health even in Fight For Your Life. Immolate is activated only if the character's health is at zero.
Ranks in Sustenance have no effect on this skill's effectiveness.
With Immolate and either the Chulainn or the Florentine, a crippled Maya can use one gun to deal three elemental damage types. Both guns on their own shoot Slag and Shock rounds. Slag interacts well here to increase incendiary and shock damage as well damage from possible burn and electrocute status effects.
Though Maya will be slagged while wielding the Chulainn, this is negligible during Fight For Your Life. This slag effect lingers briefly after switching weapons and may be buffered from the fully restored shield when obtaining Second Wind.
The Florentine does not slag the wielder, though as an E-tech weapon, it consumes 2 ammo per shot.
Immolate is triggered when Maya's health is at zero, and zero health can be achieved outside of Fight For Your Life with items carrying penalties to maximum health, namely a combination of a Hoplite and a Banshee class mod (which can furthermore increase ranks in Immolate). Maya will be protected only by her shield (which she can switch after achieving zero health) but will also deal the greatly enhanced fire damage normally reserved for down-state. Players may consider using an Amplify Shield and fire weapons whose damage can be more than doubled with 11 ranks in Immolate.
