prolly no since boxes drop 3 rarities: https://steamuserimages-a.akamaihd.net/ugc/1732172045149893501/5E91B3D38...

or that what i think, but tbh i never have paid attention when destroying 1 single box if you get 3 rarities like 3 crystal fire + spark then that mean they indeed drop 4 but it must been one single box. in my previous screen i have 3 orbs from one box so thats why i assume you only get 3 rarities per box
i kinda have quite my collection of those rare events.
