Currently (R25 in November 2015) armor merely protects your player-character from the impact of physical hits from creatures, reducing the damage inflicted on the character. Lumite armor is the fifth (tier) and best armor-type that you can craft in Creativerse. You cannot find any already crafted Lumite armor-pieces in the game currently (except for those crafted by other players perhaps). The crafting recipe for Lumite Armguards is unlocked when taking or crafting Diamond Armguards for the first time, which was unlocked by taking Iron Armguards.
