Recipes to get the item / Using this item for combining a new item[]
To get this one, you cannot get this by combining, but you need to buy at Astraea's Bastion. There is a store with full of armory / shield(s) / weapons, that can be called as the Weapon Store.
To use this item to get another item, the recipes are follows:
Leather Sleeves + Golem Talisman = Golem Sleeves
Plate + Leather Sleeves = Plate Sleeves
So this would be more protective than the Leather Sleeves.
