Shields & Shoulder
Shields and Shoulders are two different parts, but offer mostly the same stats. Some stats are nerfed on one of the pieces to prevent stats being boosted to overpowered levels. They can be looted in Sector and traded between players. There are plans for their stats to be overhauled for better customization and access to more stats in the near future.
Rare Shields & Shoulders
Macro Moon & Star | Flameward & FireScreen
These items were only sold for a limited time during Ohka BOTS beta in the shop and will not be returning. They offer unique stats but there are plans for all other endgame shields & shoulders to be reworked to offer the same stats, making this event set primarily cosmetic.
