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.
      • Added in Repentance Sharp Plug's heart cost is one half-heart per charge slot filled. The health cost is not increased in later stages where half-heart damage is upgraded to full heart.
    • Removed in Repentance If the item has any charges, the Sharp Plug will not work.

Notes[]

  • Removed in Repentance If Isaac has less than two Black or Soul Hearts, it will remove them but will not remove any Red Hearts.
  • Added in Repentance Sharp Plug attempts to draw from Red Hearts first.
  • Added in Repentance Sharp Plug cannot deal fatal damage. If used at one half heart, it will not work.

Synergies[]

  • Added in Repentance Damage-triggered items: Each half heart used up by activating Sharp Plug triggers damage effects separately, allowing multiple payouts.
  • Added in AfterbirthGlowing Hour Glass Glowing Hour Glass: As long as Isaac has more than Removed in Repentance 2 full hearts or Added in Repentance 1.5 hearts, time can be rewinded indefinitely since the health used to recharge the item is refunded upon use.
  • Removed in Repentance Keeper Keeper: The Keeper takes only one heart of damage.
    • Added in Repentance Expends health for charges at the rate of 2 charges per 1 Coin Heart. If an item is 1-charge, removes 1 Coin Heart.
  • Added in Afterbirth †Schoolbag 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.
  • Added in RepentanceTainted Magdalene Tainted Magdalene: Tainted Magdalene's Yum Heart Yum Heart can be used infinitely, allowing for infinite invincibility frames from taking damage. Paired with Tainted Magdalene's melee attack, this can easily win a run.
  • Removed in Repentance The Wafer The Wafer: Reduces the health cost to half a heart (except for Keeper).

Interactions[]

  • Removed in Repentance 9 Volt 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.
    • Added in Repentance 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.
  • Added in RepentanceAlabaster Box Alabaster Box: Expends up to 6 full hearts if possible with no charges given.
  • Added in RepentanceBethany Bethany / Tainted Bethany Tainted Bethany: Soul/blood charges are used before Sharp Plug when available.
  • Added in RepentanceEraser Eraser: Attempting to recharge the Eraser with the Sharp Plug fails and only hurts Isaac for half a heart.
  • Removed in Repentance Holy Mantle Holy Mantle: Holy Mantle blocks the damage from Sharp Plug if the shield is active, but also keeps Isaac's active item from charging.
    • Added in Repentance Bypasses the Holy Mantle and gives charges as usual.
  • Removed in Repentance Isaac's Heart Isaac's Heart: Renders the Sharp Plug unusable.
  • The Lost The Lost: No benefit from this item unless he has a respawn item because his active item's charge will not refill if the Holy Mantle Holy Mantle effect activates. Sharp Plug only activates upon receiving actual damage.
    • Added in Repentance No effect, as The Lost doesn't have health.
    • Added in Repentance When turned into The Lost via the white fire, activating Sharp Plug will take the health cost from the original character's health. Holy Mantle Holy Mantle will not block the health cost.
  • Removed in Repentance Added in AfterbirthMega Blast Mega Blast: Sharp Plug will not work with Mega Blast.
    • Added in Repentance Works as intended, giving 1 charge per half a heart.
