Ninja armor

Ninja armor or Ninja set is an armor/vanity set made up of the Ninja Hood, Ninja Shirt and Ninja Pants. King Slime drops each piece separately (1 per kill with a 1:3 chance each), or two pieces from the Treasure Bag it drops in Expert Mode. In the, pieces of the Ninja set can also be acquired from Lepus, but with only a 3% chance.

In all versions though, having the full set equipped grants an after-image movement effect, similar to Shadow, Necro, and Cobalt armors.
 * In the, it provides very little defense, but increases velocity and damage of throwing weapons.
 * In the, it provides very little defense, but increases crit chance and movement speed.
 * In the, it provides no defense, but does have throwing weapon bonuses listed in its stats. However, it does not provide the bonuses listed, and throwing damage is not a separate damage type in these versions.
 * In the, it is merely a vanity item and will provide no bonuses or defense.

Trivia

 * It is possible to replace any part of the set with one of the Shadow armor's – the after-image movement effect will remain. (It is unknown if this is also the case on the, or with other armor sets.)
