Does anyone know any ability/buff that can drain unit's health to zero? My goal is to make something like burning effect where hero's health decreases when the hero has a (custom buff) fire buff. I tried using Slow Poison ability given to the dummy unit that targets the hero but it doesn't kill the hero (it always leaves 1HP because it's a poison). I want the hero to burn when there's a (custom unit) fire units nearby and I can do that by using "Unit - Unit Within Range" Event but I can't find an ability that can give the hero a fire buff. I also tried using Burning Fuel and Flame Strike - with the use of dummy units targeting the position of the hero - but those are "Target Ground" abilities and when the hero leaves the target AOE the buff disappears, and the Immolation ability that targets self instead of the units around the hero but the ability only works when activated.
