The Dreglord starts off with a slow and simple moveset, consisting mostly of sweeps and slams.
Sweep and Slam
The Dreglord will hold its club up while circling around a player to then do a horizontal sweep and vertical slam. You can dodge through both attacks in a row.
Double Sweep and Slam
If the boss crouches down, it will do two side-to-side sweeps and follow up with an overhead slam after a delay. You can dodge the sweeps if you’re below it, but make sure to create some distance to avoid the followup slam.
Overhead Slam
The boss can do two slams in a row after a brief delay, covering a wide area below. You can run away, or dodge through the attacks.
Charge
The boss charges at a player while dragging the club on the ground, slashing upward once, and then performing four erratic sweeps with no clear target. Move to its left side and dodge through the charge, then get away from it.
Small Rot Ball Explosion
Around 80% HP, the boss gains a new move, where it will pick up a rot ball from the ground and slam it twice, dealing damage around it. The first part of the move can pull players into the boss, so run away as quick as you can.
Giant Rot Ball Explosion
Around 50% HP, the Dreglord will pick up a giant rot ball and leap into the air, making the ball explode after it flashes red. Run away from it and roll after you see the red flash on the ball to avoid the explosion, which can one-shot squishy Nightfarers.
After the attack, multiple Rot explosions will erupt on the ground for several seconds, and smaller enemies will appear.
