oki I herad alot of wep and pois. pls explain.

Is it true that I should have 200 skillpoints together to apply dp with a good chance? ex 100 wepskill and 100 pois or 120 wepskill and 80 pois?

Will it be the same if I have 105 wepskill and 80 pois + a magical item with +15wepskill? (200 skillpoints together with the magicpiece)

lets say i get 120 wepskill and 100 pois...will that be even better and more dangeroes for my enemy or does the extra 20 pois skill do any matters?

Thanks
