AFK Farms

XP Tank

Automatically stores the XP generated by every AFK Farm in the same chunk. No need to touch each one, just place it anywhere in the chunk.

Capacity

Holds up to level 30 worth of XP (1,395 points). Once full, extra XP is lost until you collect it, same as an overflowing chest.

Visual

A floating display above the tank shows your current Level and a progress bar to the next one, and the glass fills up with a rising green liquid as XP accumulates. Only shows up while aiming at the tank within 8 blocks.
