  • Removed in Repentance 15►The Wafer The Wafer: Reduces the health cost to half a heart (except for Keeper).

Interactions[edit | edit source]

  • Removed in Repentance 15►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 Repentance15►Alabaster Box Alabaster Box: Expends up to 6 full hearts if possible with no charges given.
  • 15►Holy Mantle Holy Mantle: Removed in Repentance 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 15►Isaac's Heart 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 15►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.
  • Removed in Repentance Added in Afterbirth15►Mega Blast Mega Blast: Sharp Plug will not work with Mega Blast.
    • Added in Repentance Works as intended, giving 1 charge per half a heart.
