If there's two or more enemies, it deals 1 damage to the whole group as well as the attack's normal damage.
Probably the least useful of the elemental effects, but it only gives +1 cooldown so you can use it to take out fast enemies hiding behind tankier ones sometimes without much downside.
It makes so if two are more enemies that are next to each other, every enemy behind the one you hit takes 1 damage. It can be useful in certain situations.
