Boon offer odds
Which boons will this room offer you, and at what rarity? Set up your run and read the exact odds.
How this works: the game's offer procedure worked through exactly (core-boon rule, linked boons, rarity rolls, prerequisites, exchanges) and checked against the game's own selection code. Base rolls before bonuses: Rare 10%, Epic 5.0%, Duo/Legendary 12%.

How a room picks its boons
- The room first rolls whether one choice is an exchange (replacing a boon you have with another from the same god).
- Until you hold a boon from a slot (attack, special, cast, dash, call), the god offers core boons for open slots; once you have one, at most one core boon appears.
- Each offered boon rolls its rarity: Legendary first, then Heroic, Epic and Rare, falling back to Common; keepsakes and the mirror add to those chances for their god.
- Duo and Legendary boons only enter the pool once their requirements are met; boons you already have are excluded.
