Jungle armor

Cobalt Armor consists of a Cobalt Breastplate, a Cobalt Helmet and Cobalt Greaves.

It grants the wearer 19 defense and is dropped by Hornets as well as Man Eaters in the Underground Jungle biome. When the whole set is worn it reduces mana usage by 25%, and grants an unlisted 10% melee attack speed. Each individual piece slowly regenerates mana.

Cobalt Armor is very similar to Meteor Armor as the sets have identical mana regeneration. The only differences are the different visual effects of the full sets,the armor level, which is increased in the Cobalt set, and the mana cost reduction, which is 5% higher with the Cobalt armor.
