Molten armor

Molten armor is an armor set consisting of the Molten Helmet, Molten Breastplate, and Molten Greaves. It has the highest defense of any pre-Hardmode armor set, but can also be one of the most difficult to obtain.

A full set of Molten armor provides the following benefits:
 * +25 defense
 * +10% increased melee damage
 * +7% melee speed
 * +7% melee critical strike chance
 * Immunity to the On Fire! debuff
 * If the full set is visible, it will leave a fire trail similar to that of the Meteor armor.

It takes a total of 45 Hellstone Bars to craft a full set of Molten armor, or 135 Hellstone and 45 Obsidian.
