1. Add random (stuff like leaping and slowness with minimal time) splash potions to the loot chests and kill all minigame
2. Make it so you can get middle tier items in the lucky block PvP boss game
3. It's very easy to jump alongside the rim of the pool and get on the gold platform at the in the get to the platform minigame (the one with the guardians, I forgot the name), so maybe add higher glass walls
