In Warhammer: End Times - Vermintide, a player could get special boons from the Quests & Contracts board that boosts them for a finite amount of time (one hour maybe?).
Such boons were reduced damage taken, increased damage dealt, extra stamina, and increased stagger. I’m not too sure but I think you could only have one boon at a time active.
It would be a neat idea to reintroduce these boons by completing special daily quests.
It just might make some of these terribly designed deeds I have piling up a little bit more bearable to play.
