I kill powerful bosses like
Jyrik Gauldurson

with 2 shots of the bow , or 2 backstabs of the daggers.

Do you think these perks are too powerfull and that it kills challenge?

Thanks

Sigh. A year in Skyrim General and all I learned is that every single ability in this game is either overpowered or completely useless.

What's your character's level? Which bow are you using? What's the difficulty setting?
