That’s the best example of how ~60 def is enough for a character to stay alive and do massive damage independent of the skill tree. That’s where the game shines. There are no right build, they are simply different. There is no need for 100 or higher def, even no need for a shield if you don’t like one. You are free to play as you wish.
A very nice challenge indeed. Excited to see if there will be any takers.
