Overloading Worm

The Overloading Worm is a stronger variant from the Magma Worm. In addition to a higher damage and health, it also summons bolts of lightning every time it burrows and unburrows from terrain, similar to the Magma Worm launching magma rocks.

A player can encounter the Overloading Worm as a Mountain Challenge portal boss, or a normal portal boss from level 16 and onward. The player will get a guaranteed encounter with him at level 12 through any difficulty, but it would not be the main boss objective.
