i have a .08 P wf and i put a ohm rune in it...i thought it was a good idea at the time. but i must add that puting enhanced damage on low base def dose not effect it alot. i would recomend the jah rune, and if you are looking for damage then go with some poisen charms, that would be the smart thing to do. you can always make up for damage with charms but the special more singled out attributes like ITD cannot be added later with a charm. so go with a jah, that would be a smart choice. and if u realy feel u need more damage and in duels, get yourself some high poisen damage charms, i find they help out very exceptionaly.
