Tiki armor

Tiki armor is sold by the Witch Doctor after you have acquired the Pygmy Staff.

The Armor itself will increase the number of combat minions you can have at once by one per armor piece and an additional one from the set bonus to a grand total of 5 at once (can be increased to 7 with the Pygmy Necklace which can be purchased at night from the Witch Doctor, and the Necromantic Scroll which is dropped by Mourning Wood). The armor also increases the damage of your minions by 10% for each piece worn, for a total increase of 30% with the full set. A full set of pygmies is able to devastate all but the most powerful Hardmode monsters.
