The bOx

The second tier of the Box achievement series. To earn The bOx, you must complete every chapter on Hard difficulty with every available class. Hard mode significantly increases enemy stats and introduces tougher boss patterns, making this a serious step up from the normal Box achievement. Completing this unlocks The bOx trinket (Wood set, Rare rarity), which spawns a lost Spirit in battle. The spirit gains +1 use whenever an allied cat dies, and is usable once per battle.

Tip: Hard mode demands stronger builds and better positioning than normal. Classes you found easy on normal may require completely different strategies at this difficulty. The bOx trinket becomes more powerful as your cats fall in battle, rewarding risky or sacrifice-heavy playstyles. This is the second of four Box achievements.
