my bad I was going by your post that you were only a 35 rdm, if you're 51+ that's a big difference ok
Staves are very important like your buddy told you, they attribute for magic accuracy and magic attack bonus of each affliated spell.
ie Ice staff
You would macro this in for paralyze for extra accuracy and for blizzard spells
You would NOT use this for fire spells as this stave would weaken it...
They don't affect potency just accuracy and boost the damage of ice nukes
If you wish, you don't have to do this but for good measure, find a good hq club and carry it around for potency if you have enough accuracy already to land the enfeeble on the mob consistently it's very important to be able to land the enfeeble at least before worry about increasing the effects.
If you can land consistently then use a club for the debuff whether mnd based or int based. Just don't nuke with them use staves for that.
