Weak & Squishy EB Necro needs help

T16 ist fine, but T17 is a 6 Portal guaranteed martyium.
Damage would be okish, but im dying to single barrage of projectiles.

AG wears Kingmaker, Leer Cast & Crit immune Body Armour
Spectres:
Spectral Leader (20% increased action speed)
Perfect Forrest Warrior (Onslaught)
Had a 3rd before: Perfect Warrior (Endurance Cry, Vitality, Immortal Cry), but no noticable difference
AG & Spectres are way more tanky than me, only died once so far.
Tryed Bone for Sprit Offering. Helps a bit but no game changer.

Used to run this ring for more damage but again, no notable difference.

Perfect Cane of Kulemak doesnt change much either.
Whats the next big thing i could change to increase my tankiness?

I saw in a vid that the dude deactivated EB after he summoned his 7 Animated Weapons.
I understand it close to double my ES, but each new AW loses his EB Buff, right?
The swords arent glowing blue anymore and look exactly like when summoning them without EB.
Whats the correct way to handle this?
(EB is linked to Awakened Enhance)

Minion instability yay or nay?
