Ignite

Weapons with the ignite special property use an accelerant to start small, intense fires on their targets. A target hit by a weapon with this special property must succeed at a Reflex save (DC = 20 + 1/2 the item’s level + your Dexterity bonus) or gains the burning condition (Core Rulebook 273) with the listed amount of damage. Gaining the burning condition multiple times from the ignite special property does not increase your burning damage—you take only the highest listed ignite damage each round. A character who gains the burning condition through other means (such as the burn critical effect, even from a weapon with ignite) does add that damage to her burning damage each round. Ending the burning condition ends burning from all sources.
