- Crafting material
Higher rarity items have a higher chance of dropping obsidian and drop more obsidian upon extraction.
Unique items can only be equipped by a single raider at any given time, even if you obtain more than one of the same item.
If a unique item is dropped from a boss, as long as you have the item equipped or in your inventory you will not receive it as a drop again. Extracting or destroying an item will allow it to be dropped again.
