This guy killed me a lot, like a lot, probably died over 100 times before beating him because I was too stubborn to level up.
So I decided to inflict the same pain upon my players and turned him into a D&D monster.
So I made him “only” CR 8, because he is an early game boss after all.
I had to create his rapid sword slashes, cane strikes, delayed impalement, jump attack the full phase 2 with his new shiny hammer. Due to the number of attacks he possesses each attack doesn’t do a ton of damage individually, but all together you’re in for a good spanking.
I also gave Saving throws to a couple of his attacks, to reflect the fact that you need to dodge roll them.
