I normally do not ask or need advice on charachter development as i pretty much have it down pat now
However I have recently come upon another couple of wizards in PvP that are able to boost thier scorching rays to at least 300 points of damage with a single ray (900 +) total while mine only crit for 234 points max (round 700 total)and im wondering how its done....
Please note that I do not care to hear how much damage your caster could possibly do i want DETAILS on how you do it,Nor do i wish to hear opinions on how scorching ray is broken this is a specific question asked to the BIG DOG casters.
Lemme shortlist what i use for enhancing my spells and please tell me what im missing ....(prolly a raid item)
lvl 14 wizard
+1 superior potency 6 scepter
Full fire specialization and crit Enhancements
Highest crit modifier available(Superior fire lore scepter in other hand)
Maximize Heighten Empower etc.....
Black scale robes
Any truthful help would be much appreciated
