Your melee attacks and abilities have a chance to viciously brand your target, dealing [ 0 * (1 + 20 / 100^(1 - 10)) ] Fire damage over 6 sec, and grant you Firestarter, stacking up to 15 times. Damage increased per stack to a maximum of [ 0 * (1 + 20 / 100^(15 - 10)) ].

While above 5 stacks, also deals 50% of its damage to you. At 15 stacks, enemies near your target suffer 10% of the damage dealt split between them. Firestarter decays every 5 sec while out of combat and fades entirely after 15 sec.
