Walnut

Walnut is a trinket added in The Binding of Isaac: Afterbirth † expansion.

Effects

• After Isaac is hit by 1-9 explosions, the Walnut will be destroyed and spawns various pickups. These may include:
  • Coins
  • Hearts
  • Keys
  • Random trinket

Notes

• Taking damage from the explosion is not required to trigger the effect.

Synergies

• Bomber Boy+5 bombs. Isaac's bombs will now explode in a large cross-shaped pattern (roughly 5 bombs explosions wide). This also affects player-spawned troll bombs.: As Bomber Boy causes 9 explosions at once, laying a bomb and not moving before it explodes will always trigger the trinket.
• Host HatA host familiar that sits on Isaac's head and has a random chance to block enemy shots and retaliate with 3 tears. Grants immunity to explosions. / PyromaniacIsaac heals 1 heart instead of taking damage from an explosive source. Adds 5 bombs.: Not only Isaac becomes immune to explosions, but the amount of required hits is reduced to 1-5.

Interactions

• SmelterConsumes Isaac's currently held trinket and applies its effect permanently.: Walnut will still only activate once after being absorbed.
