Doubt with magic claws

From what I remember the ias is calculated only from the left weapon slot ( your first claw ) so if you need more ias to reach the breakpoint then put ias if not I suggest putting whatever you are missing on

 

Also if its for trapper, then facets dont work.
The game sees traps as pets/minions and then facets dont add any dmg, same with griffon.
It will show dmg improve on stats screen, but doesnt actually add the dmg to the traps.
Best to put a nice FHR jewel with stats like str/dex and/or resist in 2nd claw.
