The Wafer

Effects

• All damage taken is reduced to half a heart.

Notes

• The damage reduction includes most sources in the game that would cause more than half a heart of damage:
  • Bombs.
  • Champions.
    • Except for the skull champions, they will deal a full heart damage even with The Wafer as opposed to only one half.
  • Sacrifice Rooms.
  • Environmental hazards such as Spikes.
  • Most self-inflicting damage items (exceptions are noted).
  • Every source of damage in (Womb) Womb/(Utero) Utero/(Scarred Womb) Scarred Womb and beyond, including all enemies, curse rooms, blood donation machines, and Devil Beggars.
  • The "HARD HARD" special seed.
• The Wafer does not prevent instant death effects such as (Suicide King) Suicide King or using The Bible on the Satan boss fight.
• Does not prevent health loss from Devil Room deals or Health Down pills.
• Despite The Wafer reducing damage to 1/2 a heart, this does not change the amount of invincibility frames granted from full/two heart damage sources.
• (Added in Afterbirth) No effect with (Keeper) Keeper or (Added in Repentance) (Tainted Keeper) Tainted Keeper, as Coin Hearts cannot be half hearts.
• (Added in Repentance) Does not reduce the damage taken when opening the door to (Mausoleum) Mausoleum/(Gehenna) Gehenna.
