Getting into the Grudge Pit

We will cover delve events, optional bosses (rares), as well as end of the dungeon boss and their abilities.

Events and Trash Mobs in the Grudge Pit

3.1.

Event #1: Arena Champion

In this event, you will participate in the sporeling's arena championship, where you'll fighters through waves of mobs until you face the Arena Champion - the final boss of the Delve.

In this variant, Sporbits from The War Within are back to help you deal damage to arena mobs.

3.2.

Event #2: Dastardly Rotstalk

In this event variant, you're entering the Arena as the Dastardly Rotstalk, a heel wrestling character. Upset the audience by punting fans, defeating fan favorite fighters, taunting the crowd and more.

You're able to move while taunting the crowd.

Event #3: Lightbloom Invasion

In this event, you must help with an invasion of Lightbloom mobs. It goes through several waves, involving freeing fighters blowing up spawners and building defenses.

Brightthorn Boss Guide

Brightthorn is the boss of the Lightbloom Invasion event of the Grudge Pit. This is one of the easier Midnight delves bosses, with a very straightforward ability rotation; here is what you have to do to defeat her more easily:

  • Solar Charge Icon Solar Charge has Brightthorn charging in your direction, you can simply sidestep it. Solar Charge also leaves overbloom void zones on the floor that deal damage when stood on, so make sure to avoid them.
  • Bloom Thorn Icon Bloom Thorn is a simple holy damage ability and can be interrupted.
  • Blinding Burst Icon Blinding Burst has Blightthorn burst in holy light, disorienting anyone who's looking at her at the end of the cast. To avoid the disorient, turn away from her.
5.

Gyrospore Boss Guide

MISSING is the boss of the Arena Champion event of the Grudge Pit. This boss is a little harder than Brightthorn, but its abilities are also pretty easy to deal with; here is what you have to do to defeat him more easily:

  • Fungalstorm Icon Fungalstorm is Gyrospore's main ability - He spins around the room for a few seconds, dropping void zones in the process. After Fungalstorm is done, Gyrospore becomes dizzy, taking increased damage for 10 seconds.
  • Fungsplosion Icon Fungsplosion has Gyrospore explode in AOE damage after a few seconds. As the damage is near his melee range, step back to avoid the damage.
  • Fungal Charge Icon Fungal Charge is a simple charge in your direction - Side step once you see the cast and you'll avoid it.
6.

Mycomight Boss Guide

MISSING is the boss of the Dastardly Rotstalk event of the Grudge Pit. This boss is definitely the easier of the 3 delve variants; here is what you have to do to defeat it more easily:

  • MISSING gives you an AOE effect where you'll drop a poison cloud on the floor after a few seconds. Make sure to drop it away from the area you intend to fight Mycomight at, as standing in the poison cloud slows you and deals moderate Nature damage.
  • MISSING sends shockwaves across the arena that deals heavy damage and stuns anyone caught on. They're pretty easy to spot, so make sure to dodge!
  • MISSING has Mycomight fling a literal chair on you, with a knockback and disorient if you get hit. Sidestep the impact area.
