I was thinking for a good item in a crate, you could make a sword called "Overloaded Sword" as the 40 key reward. This suggestion would be Hard to make with coding but could make the mana community happy. So the idea is a sharpness 4 sword but every hit in a combo it goes up 1.25x in damage and a max combo of 5-10 (your choice). This means that the sword gets higher in damage every hit but once YOU'RE hit it resets back to the start, in my opinion this would be a great crate item. Thank you for your patience!
