I’d like to get some info on this as well. Because without knowing this, it’s impossible to know what’s optimal. I can do harder stages, but I have to take into consideration the additional time it takes to run the harder stages and see if it’s worthwhile.

Is there a higher drop chance obtaining a 5 star epic on stage 15 of a dungeon vs stage 12?

Yes of curse, higher stage you beat bettere will be a drop rate.

Maybe you can drop at stage 12 only the 5 star rare or the 6 stars rare but you will never take an epic 5 stars but 4 stars for sure (it's an example and experience in game).
