An opinion you're probably all alone with?

Assuming you mean magicka point, I am confused about how this is possible, given that Ogrim have at least 170 hp and spell cost doesn't decrease with better attributes or skill. Did you mean spell, or bar?.

Bound Bow, 15 seconds duration. Costs 1 magicka, and with the ridiculous damage output of that weapon, most mid-level enemies are one-hit killed.
