It's a new currency. Whenever you defeat an enemy, the player who deals the final blow receives Mana Orbs.

0-50 Mana Orbs are dropped from every enemy. Bosses drop 250-750 orbs, while Ancient or Special Bosses drop 1000-5000 orbs.

Once 500 are collected in total, the Shop is unlocked for everyone.

Scratch sells base weapons, upgrades and chests. However, Scratch only sells Wooden and Golden chests with better contents.

There's another shop, too, but you won't be able to go there yet.

Keymaster Keys are also obtainable from enemies, but normal enemies have a 10% chance of dropping one.

Bosses drop at least two, and they also have a 50% chance of dropping a third key.

Special Bosses give 5 keys, with a 25% chance of dropping a sixth.

Collect 5 in total, and you'll unlock the Treasure Room. This room contains special Diamond Chests that contain better loot, but they require a key to unlock.

Also, every 25th chest you unlock gives you free access to a special chest...
