I sincerely hoped this hasnt been asked here before, but it's been something really nagging at me that I've found quite difficult to test.
In short, I'm wondering of the -exact- mechanics of Wand DPS and precisely what additional stats, if any, will increase that (via crit/hit/penetration etc). Now, noone will be making any raid-specced Wanders anytime in the near future (unless I'm really bored...) but the lack of information around on what actually affects wands is staggering, so hoping some of you guys know.
It's well known that Spelldamage does -not- boost wand dps.
Most people assume that DPS of a wand is simply the listed DPS on the wand, multiplied by 125% if a mage/priest has Wand Spec, with the weapon skill (levelx5) of the wander being used to work out Hit and Crit. Wands can be resisted, they can Crit, they can be partially resisted, so the mechanics are in there somehow.
But... i've heard all sorts of weird rumors about wanding. Some say that they count as a ranged attack and as such -agility- of all things will increase the crit rate. Some say they count as pure spells and +Crit and +hit on your items will also affect wands (so someone wanting to churn out the most dps possible would wear a pure hit/crit setup with zero spelldamage, if such a thing exists). And spell penetration? Would that affect it. I think the major crux is whether wanding is counted as a ranged attack like a bow or has some elements of being a spell.
Curious thread, but it's annoying me. When I tested it at 60 it -seemed- to imply that Spell Hit and Spell Crit -did- affect the calculations of your wand, but the gear available to test was quite limited (we did some tests with cloth with +agility on and that seemed to boost wand crit too...) Anyone know what the calculation runs off?
Shadow Weaving and other debuffs that go on the mob will increase damage. Self buffs have no effect I have seen. Not sure about hit/crit gear. Fairly positive it goes by your normal spell crit rate, so would make sense for hit to be the same.
Agility and RAP wont affect wand DPS. For awhile after release it did indeed scale with RAP but this turned out to be an oversight by the devs and was fixed in some patch around 18 months ago. Perhaps it could partly explain why there are still some low level cloth items with int and agility etc on them.
One thing I've just found out: Wanding will use up Furious Howl, which is a buff given by certain hunter pets to increase damage on your next attack, can be applied to wands. I haven't tested it to see if it actually increases the damage, however.
