Sharp Straw

Effects

• Damages all enemies in the room.
  • The damage dealt is equal to Isaac's current tear damage plus 10% of the enemy's max health.
• Has a 15% chance to drop half red hearts when it damages an enemy.
  • (Removed in Repentance) May also drop half soul hearts. Half red hearts will always drop when the player has at least one red heart container; otherwise, half soul hearts will drop.
  • The amount of enemies damaged does not improve the chance.

Notes

• When used on Delirium, this item should be used when it isn't transformed to deal the most damage, as Delirium doesn't have his armor up when in his true form.
• For enemies that can disappear or go underground, it only affects them if they are visible.

Synergies

• (Added in Repentance) Book of Virtues: Enemies have a chance to spawn wisps when they’re killed by Sharp Straw. Using it in a room with no enemies does not grant a wisp. Despite Sharp Straw having a timed charge, the wisps persist between rooms.
• Car Battery: Damage is doubled and two half hearts may be dropped.

Interactions

• (Added in Repentance) Ipecac: Only provides a +2 damage bonus instead of +40.
