Sharp Plug is a passive item.

Effects

• If Isaac's current activated item has no charges, attempting to activate the item fully recharges it in exchange for two hearts of Isaac's health.
  • If the item has any charges, the Sharp Plug will not work.

Notes

• If Isaac has less than two black or soul hearts, it will remove them but will not remove any red hearts.
• The Lost does not benefit from this item unless they have a respawn because their active item's charge will not refill if the Holy Mantle effect activates. Sharp Plug only activates upon receiving actual damage.
• When used by Keeper, it will only drain one coin heart.

Synergies

• Schoolbag: Both held active items are recharged.
• The Wafer: Reduces the health cost to half a heart (except for Keeper).

Interactions

• 9 Volt: Renders the Sharp Plug unusable. Sharp Plug can only be used if the item is at 0 charges, but 9 Volt instantly gives 1 charge to the item upon activation.
• Holy Mantle: Holy Mantle blocks the damage from Sharp Plug if the shield is active, but also keeps Isaac's active item from charging.
• Isaac's Heart: Renders the Sharp Plug unusable.
• Mega Blast: Sharp Plug will not work with Mega Blast.
