Just wondering what weapon stats effect your spell damage and casting speed? I just started levelling my thaumaturge and decided to setup a parser for the first time. After getting a new level, i equipped a couple pieces of gear and a new weapon and noticed my dps had dropped from pretty consistent 15 to 11-12 and casting speed seemed to have increased (I say seemed because i didnt actually check how long each cast was before).

None of the clothing had anything but 1 or 2 extra int/vit and maybe 1 of some other secondary stat. The new weapon had 2 extra damage + 1 vit/crit and a higher delay/auto value as its all around lvl 12ish. Cant see any reason why my damage would drop, not obsessing about dps at this level but would just like to know what is happening and why.
