Magicslime Balloon

It’s the unique equipment of Magicslime City Area 7: any monster you defeat there can drop it. As a piece of the Magicslime Set it never drops at random.

Its effects count every hero’s level of it together: with all 6 heroes at level 10, 60 in all, Rare Material Drop Chance (Global) + 0.015% becomes Rare Material Drop Chance (Global) + 0.021%. Disassembled, it gives Onyx Shards, like every Rare jewelry. Once you’ve had one, you can craft more from the equipment dictionary when the Blacksmith reaches level 70: 55,000 Onyx Shards at first, more as your heroes level it.
