Baptism of fire is stupid

I am going for a no kill playthrough. Why am I forced to kill a boss when I am going for speech and charisma?

It kind of ruins the bard experience. There should be a way to persuade others to kill him or another way around that.

Got light armor and the boss is 2 hitting me.

The game forced me to wear heavy armor and to shoot 1 better piercing arrow in his face. One shot and he died.

Really this mission sucks so hard …

Luck you can get to the boss lol
