The aa doesn't work on spells that are already less than 3secs casting. And it lowers whatever it does work on by 50%. Doing 'inspect' on the ethereal brand says 3.75sec (1.875secs). Claw is 3secs (1.5secs). According to the inspect on spells.. the tribute spellhaste power of alacrity doesn't have any effect on casting time afterall. The spells have the same labels. My logs don't do decimal seconds so I cant really tell if it does have an effect but just not show in the spell inspect. Or is it as I fear, that spellhaste is capped at 50% no matter if you use the spellhaste tribute. It seems to me this tribute should work. Oh, and the spellhaste I have from clerics doesn't seem to do anything either for the same reason (on 3+ spells).
