When the new miniboss of Splintershard, Magmoo, does his jumping ground slam attack lava pillars come out of the ground. This also involves the horizontal line of lava pillars he summons after a lower health threshold. These lava pillars currently do zero damage to the player despite all of magmoos other attacks involving fire doing damage.
Steps to Reproduce
1. Let magmo summon the vertical lava pillars from his jumping ground pound attack and two handed smash attack.
2. Notice how these do exactly zero damage to the player
