Palladium Bar

Palladium Bars are a Hardmode item made from 3 Palladium Ores. They are the Cobalt Bar's counterpart.

Crafting all Palladium equipment requires 174 Palladium Bars, or a total of 522 Palladium Ore.

Trivia
Palladium, being cobalt's counterpart, is more medieval Europe based, with knight-like helmets, weapons, and armor.
 * Real-life palladium is actually a lustrous white metal, and is nowhere near the color in Terraria. However, many palladium salts have a bright orange color.
