Ultris Bug Fixes
Java mod listed for Minecraft 1.20. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
A tiny, simple addon mod for Ultris: Boss Expansion that fixes a few bugs
It currently fixes:
- Using Corrupt Dust on an enderman. Before then, provoking a fight with the Corrupted Enderman when converted using Corrupt Dust has it cut straight to its desperation phase. With this mod installed, using Corrupt Dust will finally have the fight initiate properly the way it should.
- The Corrupted Enderman's boss bar max value not actually matching the max health value of the boss, causing the first few blows against it to not budge its boss bar at all.
- The Ultra Wither's command block having a hitbox of its own with active collision, which can obstruct the boss's own wither skull projectiles.
Please let me know if there are any other bugs pertaining to Ultris that I have yet to take care of!
