Hello guys. I am new in this game. This is my first build and I would like to know what you think.
I wanted to get as much benefit as I can from CDR.
Tell me what kind of mistakes I have made.
I will be glad for any response 
It really comes down to how you play the game. I wouldn’t do what you did as it’s too low on health regen for my taste, and I’m not sure the shields from tortoise and crab really add up to that, but maybe I’m wrong ? You seem to play ranged given your weapon and skills used, that may help.
That said if you wanna go full CDR you better reach Aeon’s Hourglass, very defensive devotion and the proc is huge.
For your skill points it seems a bit too spread out, maybe removing those one point wonder you put at various passive skills and add more to Amarasta since you bound it to left click ? I dunno, it may needs some playtest first.
