Added in Afterbirth †

Sharp Straw is an active item added in Afterbirth †.

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[]

  • 15►Car Battery Car Battery: Damage is doubled and two half hearts may be dropped.

Interactions[]

  • Added in Repentance15►Book of Virtues 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.
  • Added in Repentance 15►Ipecac Ipecac: Only provides a +2 damage bonus instead of +40.

In-game Footage[]

Trivia[]

  • Before Booster Pack #5, Sharp Straw would instantly kill Big Horn if used while his hands were out due to their arbitrarily high health.
  • Sharp Straw was originally an unofficial item which was supposed to showcase the modding capabilities of Afterbirth+ in the PAX 2016 livestream. However, all items included in the demo were later added to the final game.
    • In the livestream, Sharp Straw had the name 'Isaacula', a different appearance, and a recharge time of six rooms.
