Armor: Green Dyed Leather Helmet, Iron Chestplate, Gold Leggings, Diamond boots
Description: You are a villager chief, and used some armor and emeralds for war. Right click emerald to throw emerald and knocks whoever you hit!
Emerald Barrage: You throw out 1 emerald every 0.25 seconds for 6 seconds. This does high kb but only 0.25 damage per emerald.
