Magma Worm

Tactics
The Magma Worm has a single attack in which the worm emerges from the ground, turns around and resubmerges. The worm leaves a small patch of flame whenever it emerges or resubmerges. When fighting the worm, it is difficult to fight with other enemies around, as you may be forced to dodge into them. Climbing onto a rope or vine can prevent all damage this worm deals, as it only deals damage through contact when it goes up or down. This is an advantage for engineer's Thermal harpoons. This boss can be very easy to kill with AoE abilities or abilities that hit more than one target, such as the Mercenary's and, and the Huntress'  and , because the worm has multiple segments that can be damaged. When on low health, the worm will strike faster and move faster, but will become less accurate.

On death, the worm may drop the Burning Witness item.
