Ermyst Chestplate

The Ermyst Chestplate is an armor added by The Mists of RioV 2 mod, now The Mists of RioV. It can be upgraded via Enhancer to get the Ermyst Chestplate Tier II, or be enchanted normally. Do note using an enchanted armor piece in the Enhancer will wipe away it's enchantments in the upgraded version of the armor.

As the Tooltip Text indicates, wearing a full Ermyst armor collection gives the player Haste III as long as the set is still worn.
