Rolling Magma (previously known as Magma Orb) is a spell skill that launches a projectile that bounces on a parabolic curve that explodes on impact dealing fire damage in an area of effect. Effects that modify the number of times projectiles can chain changes the number of times Rolling Magma's projectile bounces instead.

Skill functions and interactions

• Rolling Magma'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 then bounces in the same direction that it was initially launched. The impact has a base radius of 14, and a base spacing between impacts of 16. The projectiles do not collide with enemies; damage is only dealt when hitting the ground.

However, the explosions from Rolling Magma's splashdown do not overlap, meaning that each time the orbs strike down at the same time, damage is dealt only once to any given enemy. Spread of the projectiles can be controlled by targeting closer to or further way from the caster.
