Ninja armor

Ninja armor is an armor set made up of the Ninja Hood, Ninja Shirt and Ninja Pants. Each piece is dropped separately (1 per kill with a 1:3 chance each) by the rarely-spawning/summonable King Slime, or two pieces from looting Treasure Bag dropped by him on Expert mode. Lepus (mobile only) also has a chance of dropping pieces of the Ninja set, but with only a 3% chance.

Having the full set equipped grants a After-image movement effect, similar to Shadow armor, Necro armor, and Cobalt armor.

Ninja armor is very useful with the Bone Glove.
