Effects
- While held, Extra Vessel can be filled by picking up a
Red Heart, and takes damage first before the rest of Isaac's health bar.

Notes
- Extra Vessel can not be filled by a
Rotten Heart or
Morbid Heart.
- Damage taken with the trinket filled does not reduce the chance for
Devil Rooms or
Angel Rooms to appear.
- The trinket effectively grants a Red Heart container to characters who can not have them (
???,
The Lost,
Dark Judas,
Tainted ???,
Tainted Lost,
Tainted Judas, and
Tainted Forgotten ), allowing them to use Red Hearts for health.
Keeper and
Tainted Keeper will not be able to be fill Extra Vessel outside of co-op, as all Red Hearts that appear are automatically turned into
Blue Flies.
