Sharp Plug is a passive item.

Effects

• Damages Isaac in exchange for fully recharging Isaac's current activated item.
  • Sharp Plug costs two hearts of health to use.
    • Sharp Plug's heart cost is one half-heart per charge slot filled.
  • If the item has any charges, the Sharp Plug will not work.

Notes

• Sharp Plug attempts to draw from Red Hearts first.
• If Isaac has less than two Black or Soul Hearts, it will remove them but will not remove any Red Hearts.
• Sharp Plug cannot deal fatal damage. If used at one half heart, it will not work.
• on the mobile version sharp plug is impossible to activate In any way during regular play

Synergies

• Keeper: The Keeper takes only one heart of damage.
  • Expends health for charges at the rate of 2 charges per 1 Coin Heart. If an item is 1-charge, removes 1 Coin Heart.
• Schoolbag: The active item in the main slot is fully charged as normal and the secondary slot gains as many charges as the main one did.
• 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.
  • As Sharp Plug can now be used with charges and the cost is based on charges filled, 9 Volt now synergizes with Sharp Plug, lowering the cost of using it by half a heart on 2+ charge items.
• Alabaster Box: Expends up to 6 full hearts if possible with no charges given.
• Holy Mantle: Holy Mantle blocks the damage from Sharp Plug if the shield is active, but also keeps Isaac's active item from charging.
  • Bypasses the Holy Mantle and gives charges as usual.
• Isaac's Heart: Renders the Sharp Plug unusable.
• The Lost: No 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.
  • No effect, as The Lost doesn't have health.
• Mega Blast: Sharp Plug will not work with Mega Blast.
  • Works as intended, giving 1 charge per half a heart.
