Question about blink/mirrow arrow mechanics

I'm looking into making a trap/minion instability mirrow arrow build. I was just wondering if anyone has any insight to the mirrow/blink arrow gem because I have not found any answers:

-Do the minions benefit from gear you are wearing i.e. belly of the beast or other % HP items like bubonic trail to increase base HP? How about gear with socketed abyss jewels?

-Does your character's base HP have a determination of what HP the minion spawns with?

-The wiki provides that level 88 has 4225 hp. Is this level determined based on the map or the level of the gem? Can mirrow/blink arrow spawn a clone higher than level 88 if the gem is leveled higher than 20 w/ corruption/empower?
