Happy Gongsgiving is supposed to give 400 gems when played on ultimate, but I only received 150. Took a picture for you on a teammate’s account to show that the Adventure grants all lower difficulty rewards when played (so 400 gems), but instead only granted the 150 from Ultimate. I’ll include my personal info, although I suspect this has probably affected everyone in the community, or at least on PSN.
This has always happened to me in adventures, I interpreted it as “awards” referring to what you managed to win after battles or in chests. Anyway, if it weren’t like this, the value of gems presented would then be the total of the sum of the minor difficulties.
If this is not the case, any deposit you make into my account worth all the gems I would have won will be greatly appreciated!
The only difference between difficulties are the final rewards, the ones specified in that screen (usually gems, but sometimes coins as in rune hunters or spell shards as in wizards circle). When you finish the adventure, you get the reward corresponding to your level in a replayable adventure, and the reward corresponding to your level plus all the lower ones in a non replayable adventure.
That means that in this adventure (which is non replayable) veteran final reward would be 50+25=75 gems, champion 75+5+25=150, master 100+75+50+25=250 and ultimate 150+100+75+50+25=400. However, we are only getting the level reward, as if this adventure was replayable (which it isn’t).
