Hm, I did a comparison of this kind awhile back and found that a higher staff is better than a lower staff for a cleric/priest because LUK affects the Heal formula more than base INT does.
But for all base-spell-attack based skills, LUK does nothing while INT gives a small static increase (static relative to spell attack anyway). So a Wooden Wand is actually better than a Dragon Staff, both clean.
Mage damage formula wasn't thought through very well, IMO.
