Leech Supreme

The Leech Supreme is a boss in the Rift. It lives in the Leeches Lair, which Dr. Edwin lets you into once you have finished his quest, and only while the boss is alive. It respawns 40 seconds after it dies.¹

How the fight works. It mostly hits you in melee, and every attack drains a share of your remaining Rift Time. Each time it loses 160 health it flies to the edge of the arena, turns invulnerable and starts a new phase:¹

1. Slime Pound: a slime ball slams down somewhere in the arena seven times, sending out shockwaves you can jump over.
2. Wicked Bombs: bombs land at random and at you; green clay on the floor marks each blast area.
3. Leech Swarm: Leech Swarms and Leech Alphas pour in, more for each player in the fight.
4. Mortiferous Lazer: a laser sweeps across at jump height, then comes back one block higher. Jump the first pass and crouch in the marked hole for the second; the hole moves each time.

Beating it sends you to the Lagoon Hut.¹

Tips: standing at -146.5, 31, 71.5 avoids both Slime Pound and the laser. In a group, only one player should enter until the swarm phase ends, since the number of leeches grows with the players in the lair.¹
