nice and for a hth weapon I have a chaos plus drain health dragonbone sword- chaos fueled by maxed destruction damage mods and drain health 70 points per hit from maxed restoration. SWEET!!!
Putting these two enchantments on all of my weapons has always been a goal of mine. I've usually failed to do it because I didn't have the chaos enchantment or I broke some major quests and had to start a new game before I got my enchanting high enough. Of course, putting these enchantments on Stalhrim is best for the enchantments since it boosts Chaos.
The chaos enchant is tagged as a frost, fire and shock enchant. Anything that benefits fire, shock or frost will add to the chaos enchant.
I have put chaos and frost on my bow.
On an unrelated note, the base damage, not sure why, is greater than my dragonbone bow (622 to 570)
