 "Tyranny" uses a skill-based growth system rather than a class-based one as with "Pillars".Heins said that they wanted to allow players to find ways to play a character they wanted instead of forced into a defined class.They also wanted to make sure that players could work to revamp characters mid-way through the game without penalty, avoiding the situation where a player may have built out a character that is difficult to use to progress into the late-game.
