Fae guardians/ mask

Hello, i recently switched to night fae . This legendary seems pretty cool becuase it gives back mana but i am confused on how to use ot porperly to be honest . I would like for someone to help understand how to send the fae guardian’s out to other players using vuhdo preferably and if there is a way to monitor wich guardian is on wich target in vudho? Also,the mask abitly is that something that i have to control as well or?

I just make a Marco to cast it on the start for the cdr. For the shield I put it on myself most of the time. I also use vuhdo.
