Magma Worm

The Magma Worm is a returning Boss Monster in Risk of Rain 2. Being a Boss, the Magma Worm may be encountered after initiating a stage's Teleporter Event. It can otherwise spawn naturally during higher difficulties.

The Magma Worm has a stronger variant, the Overloading Worm. The Overloading Worm is not considered an Elite Magma Worm, but rather a unique Monster.

Attacks
Magma Worms do not attack players in the same vein as other bosses. Magma Worms' primary form of offence is to ignite targets that make physical contact with it. Each time the Magma Worm emerges from the ground, the screen changes color to a bright orange to signify the heat. Instead of traditional attacks, the Magma Worm instead has multiple modes of movement.

All "attacks" has a Proc Coefficient of 1.0.

Leaping
The Worm will erupt out of the ground and launch itself into the sky, before burrowing back into the ground. The Magma Worm will attempt to emerge from the ground close to its target to ignite them, and it will aim at a target as it returns from the sky. As the Worm exits and enters the ground, it will cause molten balls to erupt from the ground which explode on impact can deal damage.

Grounded
The Worm will snake quickly from the ground and remain in close proximity to its target. While a leaping Magma Worm will remain airborne for quite some time, a grounded Magma Worm will rapidly enter and exit the ground as it assaults the player. With that in mind, molten rocks do not erupt from the ground in this mode of movement.

Tips

 * It is advisable to fight Magma Worms in wide open spaces, as fighting them in cramped spaces can be troublesome. For example, in Rallypoint Delta's caves, when the Worm is leaping you are not only unable to efficiently damage the boss (as it continuously disappears into the rock above), but you are unable to see where the Worm is about to land as it burrows back into the ground. In a situation where a Magma Worm is spawned from a Teleporter placed in an unfortunate position, it may be a good idea to lead the worm to a more suitable fighting area before returning to the Teleporter area.
