Pockets

PocketsMC is an orb-grinding server for Java Edition.
 
You smash orbs for XP, Lint and Shine, then spend it on better swords, armour and bundles. Each floor has five rings of orbs. The outer rings unlock as your Space level goes up, and the road ends in the middle, where the floor boss is waiting.
 
Bosses drop their own Lint, and you need their gear to reach the next floor. Cragmaw is a Ravager sitting in the pit. Shardseer is a crystal wizard whose Mirror Shot kills you in one hit unless you block it. Bring a shield.
 
Once you’re past floor 2 you can Rebirth. Bosses also drop accessories for your bag. Trading goes through the Auction House or buy orders, and every floor has its own Talisman and Elytra shop. If you link your Discord, /daily pays out too.
 
PvP is off unless you turn it on, so nobody can jump you while you grind.
