Well... For my very personal experience lv1 warrior sux big time with this sword... I have yet to done my drk quest yet, magic kill doesnt count...
Since you will not be using WAR after you acquire DRK, I do not suggest you lvl that to anything near 18 nor 30... Just start as a thief, get your sub at lv18, change into war/thf lv1, lv that your war to lv10-15. Then switch back to your thief and lvl to lv30... After that, with a decent lvl on warrior I believe you will have a much better luck with killing bees with that shitty lv1 d3 delay666 2h sword...
