Behavior
Magma Worms do not attack players in the same vein as other bosses; their primary form of attack is to targets that it makes contact with. Each time a 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 have a proc coefficient of 1.0.

Leaping
The Magma Worm erupts out of the ground and launches itself high into the sky, before burrowing back into the ground once more. It will attempt to emerge from the ground close to its target to burn them, and it will aim at a target as it descends and prepares to burrow again. Wherever the Worm exits or enters the ground, it causes molten fireballs to erupt from the ground, which explode on impact.

Grounded
The Magma Worm burrows quickly in and out of the ground and remains in close proximity to its target. When it moves like this, it does not cause fireballs to appear.

Tips

 * It is advisable to fight Magma Worms in wide open spaces, as fighting them in cramped spaces can be troublesome.

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.
 * Marking the Magma Worm (middle mouse button by default) can help keep track of it when it travels inside terrain.
 * Because of how much ground they traverse compared to other enemies, it is possible that Magma Worms may change targets mid-attack if a new potential victim comes into range. This might be another player, or even an unlucky turret.
