New modes and reward buffs/difficulty decreases
I'll start by saying when it's good, incursions is a really fun mode however that fun is short lived through kinda bs AI and stuff in the way so I propose a new Roguelite.
Start off with one champ at 1 star which you fight through areas to build them up or replace and add new champs to do the same. Each time you clear a zone you pick to add stuff to one of your champs or pick a better one.
This continues till 7 stars at this moment in time with them being the highest.
