Flammability (debuff)

[[File:|link=|alt=]]

Flammability is a Debuff that provides the chance for Hits to Ignite the target. It is not itself an Ailment, but is closely associated with Ignite, which is.

Fire damage from Hits Contributes to the Magnitude of Flammability, so Hits that deal more Fire damage will Ignite more often.
The base Magnitude of Flammability is 1% chance to Ignite the target for every 5% of the target's Ailment Threshold dealt as Fire damage. Flammability from a Hit is applied before that hit checks whether it should Ignite the target, and so will affect that chance for that Hit to Ignite.

Since chance for Hits to Ignite comes from Flammability on the target, modifiers which increase the chance to inflict Ailments will increase the Magnitude of Flammability inflicted.

Effects which do not Hit targets, but Ignite as if they had, such as Ignited Ground, also inflict Flammability, but do not roll a random chance to Ignite. Such effects will only Ignite once the total Flammability on the target reaches 50%.

Multiple instances of Flammability stack, raising the chance for Hits to Ignite the target up to 100%. Each instance of Flammability has its own independent duration, lasting 8 seconds by default.

Flammability is a debuff aligned with fire damage. It adds a chance for hits that deal fire damage to inflict ignite.

Version	Changes
0.3.0	Fire Damage no longer inherently has a chance to Ignite. Instead it inflicts Flammability on the enemy based on the damage dealt. Flammability is a debuff that lasts for 8 seconds on Monsters and grants all Fire Damage against the enemy (including the hit that applied Flammability) a chance to Ignite that enemy equal to their Flammability magnitude. Flammability lasts for 4 seconds on Players.
