Murasama is a passive item in Glacier's Laboratory, a mod for The Binding of Isaac.

Cannot appear naturally. Can only be obtained by removing the seal from Sealed Katana.

While heldSpawn a red katana that swings rapidly in the direction Isaac is firing, it can unlock any door or chest and slices through most obstacles.

Hitting an enemy projectile with the katana will deflect it, which deals 1 + 2 * CurrentStage damage on hit.

Hitting a enemy with the katana deals 2 * CurrentStage damage, applies one stack of Murasama Wound to it, and inflicts Bleed, Marked, Magnetize, Paralysis, Confusion, Burning, Weaken or Slowness.

Each stack of Murasama Wound removes 1 additional health from enemies that are hit by the katana, and lasts until the enemy dies or transforms into another enemy.
