Smelter

Smelter is an unlockable activated item added in The Binding of Isaac: Afterbirth †.

Effects[]

Upon use, any trinkets that Isaac is holding are destroyed, and their effects are permanently applied to him.
- Trinkets that are absorbed show up on the pause menu and on the HUD's item tracker.
Increases the chance for a trinket to drop. (Has a 2% chance to turn the pickup variant into a trinket.)

While held, Mom's Box will double the effect of all absorbed trinkets (if their effects can be doubled).
This item can remove the Tick.
Trinkets whose effects only activate once, such as Store Credit, Missing Poster, and Walnut, will still only activate once after being absorbed.
Perfection is still removed if Isaac takes damage from regular sources.
Faded Polaroid cannot be used to open the Strange Door while smelted.
It is possible to find previously smelted trinkets during a victory lap, or if the trinket Item Pool is exhausted.
Picking up a copy of a trinket which was already absorbed will not duplicate that trinket's effect.
The trinket will not be absorbed if Smelter is activated during the pickup animation.
