The Viper School Gear itself is worth it enough to get this DLC, I really couldn't find any other armour that looked cool on him or fit his character as much as this one.
But apart from the armour set, very fun and interesting quests, and I'm happy we get to see Shani again.
The Caretaker boss was a fascinating and cool fight, but the whole cryptic concept behind O'Dimm was even cooler. Really enjoyed this DLC.
