BAMA Devouring Diadem bug minion no energy shield with Bone barrier ascendency

Equipped the Devouring Diadem and BAMA minions do not have energy shield as well. When equipped other helmet, no problem and BAMA minions have es again.
Maybe BAMA minions also benefit from equip helmet?
Currently no game breaking items that will make BAMA more OP but BAMA may benefit from Wilma's Requital to get additional attack speed. Bow crafted minions increase attack speed and cast speed will add more attack speed for minions. Quiver to craft attack speed and cast speed.
Actually this is a debuff as you cannot benefit from large minion cluster jewel 100% of the time. With Renewal requiring full hp to get 5% chance of double damage.

If that is the case, they should be able to start regenerating their es but their es never goes up. I tested it wearing normal helmet and allocating Eldritch Battery, clones have EB too. Maybe clones can copy point blank and precise technique as well but that is just wrong. Minions should not be able to copy passive tree bonuses. If they can copy then all notes that affect you will also affect them.
