#I want to make an ability called 'POISON' which inflicts Poison effect to the attacker.
#This ability is called when the enchanted mob is damaged.
on damage of living entity:
    #Checking if the victim is enchanted
    if victim is enchanted:
        #Checking if the victim has the abilty 'POISON'
        #Quick note: parsing a list as a string to check the enchantment is a rudimentary way of checking...
        #But Skript has some issues with string lists. There's no other ways in my knowledge.

            apply poison 2 to attacker for 10 seconds replacing the existing effect
