Aether Ray Question

Should I focus only on cooldown reduction, or does casting speed have an effect as well?

Cast speed is the key in any caster. CDR isn’t needed for AAR

Thanks mucho =)

For good AAR you need 4 things :
1 - tankiness , you want to shoot the ray all the time, not run around .
2 - Energy, energy regen/ %energy cost reduction . You need at least 10 second of continius cast without poition.
3. 200%Cast speed for 5 hit per second.
4. 3k+ OA .

CDR is always a nice thing to have for all Arcanist so if you have all of the above you can invest in CDR. Id say CDR worth way more that whatever %dmg you can find on gear.

I didnt know CS would affect hit per second of aar. Thanks for new info =)
