Mine U: Underwater Abyss

Underwater Abyss is one of the 26 Prison mines. It is the twenty-first mine: unlocking it costs a one-time 100,000 Prison Points, after Twisted Temple (mine T) is unlocked. Once unlocked, jump straight to it with /prison u.

Possible Pokemon

Mining here has a small chance to lure out a wild Pokemon from this pool (legendaries are far rarer than the rest):

Blocks

Every refill of the mine is rolled block by block from this weighted palette. Fill chance is the share of the mine each block makes up on average. Prison Points is what the block pays when sold inside Prison (autosell, /psellhand, /psellinv). The last column is what the block's mined drop sells for on the main server with /sellhand; a dash means it drops nothing sellable without Silk Touch.
