Rolling Magma

Magma Orb is a spell that launches a projectile on a parabolic curve that explodes on impact dealing fire damage in an area of effect.

Skill functions and interactions

Magma Orb's projectile is launched through the air from the caster's location and lands where the caster is currently targeting (up to a maximum range). This causes an explosion dealing fire damage and also launches another ball on a pre-set arc in the same direction as the first projectile. The impact has a base radius of 14.
