i used the winged twilight soulgem to enchant a daedric katana. it does like 4-44 pts of damage without enchantment. the sword will hold 18 pts of enchantment. with an enchant skill of 100, i was able to put an Absorb Health touch for 45 pts, cast on strike for 1 pt of charge per cast. winged twilight gives 300 charges. so this sword now hits for 4-44 damage plus 45 from absorb health, and can do this 300 times before recharging. which is never really a factor since most things die within 4 or 5 whacks (dremora lords and golden saints included).
