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 a 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.
