A mechanic that I really like from 13th Age is the Escalation Dice that start adding +1 from the second round of combat, until +6. This represent the escalating action and the effort PC apply in combat.
Do you think this mechanic can be replicated in Genesys?
Like for example, from the second round you always add an Advantage, third round a Success, fourth round an Advantage and a Success, third round two Successes and so on...
only PC and really special Nemeses can use this bonus, minions and rivals cannot.
What do you think? This can make combat easy for PC, but can have some drewback that I ignore?
