In one thread I’ve seen a guy posting of some ascendant system but I felt like it wasn’t for Grim Dawn. Here’s my own view of a system called the Ascendant system which would allow you to lvl up past the lvl cap but wouldn’t be infinite since thre’s no infinite scaling in GD. Something like 50-100 lvl seems interesting.
The Ascendant system would give access to a new feature/UI window. The stats wouldn’t be crazy, but significant enough for you to play more with your build. For exemple a stat could be having 500-1k life once maxed. Or maybe 5% total speed once maxed… etc.
They could even add temporary buff to it. Something like 3 different categories (or more) buff that last x second with x sec cooldown. You could only chose one! One for pure speed (berserk mod), one for pure damage (good for cooldown builds) and one more defensive (dodge or reducing damage…something defensive you know!). The berserk mod for exemple could go over the max value/cap for both run speed and casting/attack speed.
The game involve gods, maybe the ascendant system could be the idea of ascending to be one 
--> without being unkillable of course!
