The Arena
This mod adds a custom school structure to your world. Inside, you will find the three FS bosses waiting in an arena.
To start the fight, simply right-click the challenge altar/block inside the structure. This will trigger the encounter and spawn all three bosses at once. Prepare your gear before you trigger it — there is no turning back.
