Thanks alot, For those wondering this still works (on time rifts + Hero Trials + Story mode). if you use it in the arena even though it says u won, it reflects as a loss. can use on crusade mode but even though u win the stage it wont progress on to the next, so dont use it for that.
On a different note wouldnt there be a way to modify the gold/chest recieved during a stage using a similiar method?, just asking. would be great if someone can find those values to use before the stage ends n the server makes a save.
