This is an empty mod that just downloads Goorakh's maintained version.
Phase 4 can be toggled on/off in the config.
Arena visuals and purple VFX can be toggled on/off in the config.
Base stats are balanced around "vanilla" E8, increase stats or tweak attack configs to add difficulty based on your own gameplay/needs.
"Practice Mode" is activated by interacting with the shrine to your left when you spawn in on the moon. It gives you infinite revives during the fight, Phase 4 won't give you the speed buff and pizza attacks may not spawn if you die during this phase with practice mode.
The "Core of the Collective" item dropped after the fight is completed does nothing, it's there to track victories against Umbral (in the logbook) and act as a "trophy".
