Magma Worm - Boss Fight Combat Tips
Avoid Magma Worm's Impact Point
When the Magma Worm dives into the ground, you'll get a great deal of damage when you're standing at the impact point. Make sure to keep moving around & avoid this area to prevent yourself from getting killed.
Dodge Away From Magma Balls
The Magma balls that get thrown from the vicinity of the Magma Worm's impact point have small splash damage so it's best to sprint or dodge away when you see them.
Focus Burst Damage When It's Above Ground
There is a limited window when you can hit the Magma Worm - it's either high in the air or under ground. Focus your burst damage when it's coming up from the ground or going into it to lower its HP bar as much as you can.
