Item Pool Browser
Every item each of the 31 item pools can roll, with its weight
Data updated
Overview
The Treasure Room pool is by far the deepest at 407 items. Open any pool to see every item it can roll and that item's relative weight. Smaller pools are easier to read. The Devil Room holds 94, the Angel Room 66 and the Planetarium only 11. The Shell Game is the smallest at 6. Greed mode keeps its own versions of the main pools, listed as separate entries.
How it works
What this doesn't model
These are the base pool lists, so a few things are left out. Pool depletion during a run isn't tracked. Greed mode only shows up as a separate set of pools, with no other differences from normal runs modeled. Characters that change what their pools can roll aren't reflected either. And 22 items, like The Polaroid and Key Piece 1, sit in no pool at all.
