Agreed - use strongest what you have. Hit fast and hit strong. They use absorb health so for every 1hp you lose they gain 1hp. Also try drain health 100 for 1s, works well on wounded and is cheap.

The WOTW adsorb effect only works on touch range, so you can keep running away and attack with spells / arrows.
If you wanna go melee, run up, hit it once and retreat before it can attempt to adsorb from you (it'll make some sorta gurgling noise when it tries that). Rinse and repeat.
One second paralyze. Works great on everything except immunes (vampires and skeletons mostly). I call it "Suckerpunch." Several free swipes for minimal cost. And of course there's the ten second version once that becomes affordable but 1 sec works great. Paralyze, take a few swipes, recast, rinse/repeat. You actually get more than 1 second since it takes them while to fall down and get back up.
somehow I don't quite see myself running from WOTWs. They are slightly too fast for me
