Summons a rainy cloud on the final location, unleashing a rain upon targets, friends or foes.
The rain can be used to best benefit in locations with several enemies clustered together, as the projetiles will hit each of them. It can also be dropped below an x2, as the rain will end up catching it. On it's own, each individual pellet deals low damage, but if several of them hits the same target, it can do a decent amount, specially if coupled with a maxed offense skill tree.
Hail: Fires fewer projectiles than the rain, but they have a higher explosion radius and deals 7 points of damage instead of 4.
