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 MantleAutomatically negates first taken damage in every room. effect activates. Sharp Plug only activates upon receiving actual damage.
• When used by Keeper, it will only drain one coin heart.

Synergies

• SchoolbagAllows Isaac to hold two active items.: Both held active items are recharged.
• The WaferAll sources of damage that would cause more than one-half heart of damage are reduced to one-half heart instead.: Reduces the health cost to half a heart (except for Keeper).

Interactions

• 9 VoltReduces the charge of any Activated Items by 1. Any 1 charge items instead have timed recharges.: 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 MantleAutomatically negates first taken damage in every room.: Holy Mantle blocks the damage from Sharp Plug if the shield is active, but also keeps Isaac's active item from charging.
• Isaac's HeartIsaac himself is now immune to all damage, and a heart familiar appears and follows Isaac. If the heart is hurt, Isaac is hurt.: Renders the Sharp Plug unusable.
• Mega BlastUpon use, Isaac fires a laser similar to the one used by Mega Satan. This laser deals massive damage, lasts for approximately 15 seconds, and persists between rooms. Isaac is pushed backwards by the force of the laser while it is active.: Sharp Plug will not work with Mega Blast.
