Marbles is an unlockable passive item added in The Binding of Isaac: Afterbirth † (Booster Pack #5).
Effect[ | ]
- Spawns 3 random trinkets.
- Taking damage has a 10% chance to swallow Isaac's currently held trinket, gaining its effect permanently, similar to
Smelter.
Notes[ | ]
- If activated while carrying two trinkets, both will be swallowed.
- Trinkets swallowed via Marbles will not be removed or rerolled by items such as the D4.
- Perfection is still lost after Isaac takes damage from regular sources.
- Faded Polaroid cannot be used to open A Strange Door if swallowed.
Synergies[ | ]
- Glyph of Balance: Allows a trinket to appear every time there's a room clear drop as long as the other room clear drop criteria aren't satisfied, as it empties the trinket slot.
- Tainted Eden: Absorbed trinkets are not rerolled by Tainted Eden's passive effect.
- Tainted Isaac: Absorbed trinkets do not take up an item slot.
