A channeling skill, stunning the targeted enemy while channeling, slowly draining the enemy's health while healing and filling the mana of the caster. If the Enemy's health drained lower than 80%, after 5 second, It will turn into a ghoul as your minion that last for 10 second, The Skill is channeled until the enemy health to 70% or interruption. Targeted unit that has less than 20% Health will turn into ghoul after attacked by this spell.
