Energy Storage: 11+1+3
Healing Prayers: 10
Protection Prayers: 10
[Ether Renewal][Heal Other][Jamei's Gaze][Shield Guardian][Aegis][Protective Spirit][Vital Blessing][Life Bond]
Much like the standard ER-Protter, he can use high-cost protection/healing spells and actually gain energy. With a 20% increased enchantment mod on his staff, Ether Renewal will be kept up 24 of the 30 seconds. He will automatically recast it whenever it becomes available. In Hex-heavy areas, you can replace one of the spells with [Cure Hex].
Vital Blessing and Life Bond should be disabled and manually cast upon entering an area. he should maintain Life Bond on Acolyte Sousuke and the player and he should maintain Vital Blessing on himself and Acolyte Sousuke.

Acolyte Sousuke (E/N)
Energy Storage: 11+1+3
Death Magic: 10
Curses: 10
Air Magic: 1+1
[Ether Renewal][Blinding Flash][Animate Bone Horror][Blood of the Master][Enfeebling Blood][Shadow of Fear][Mark of Pain][Barbs]
A box of nastiness in one character. Blind, Weakness and some potent hexes, coupled by some decent minions. A Bone Horror at lvl10 Death Magic has the same level as a Bone Minion at lvl16 Death Magic; the difference is that you get only one at a time instead of two. Because Vekk maintains two enchantments upon him, Ether Renewal can fuel these spells with ease.

Zhed Shadowhood (E/Mo)
Fire Magic: 12+1+2
Protection Prayers: 10
Energy Storage: 8+1
[Rodgort's Invocation][Fireball][Meteor][Searing Heat][Teinai's Heat][Fire Attunement][Elemental Attunement][Life Bond]
Your standard nuker with his spare points in Life Bond, which he will use to bond Vekk. This will protect Vekk and fuel his Ether Renewal. You can replace Searing Heat/Tenai's heat with Aegis or a condition/hex removal spell if the situation warrants it. If you take the role of Vekk yourself, you can replace Life Bond with something useful like [Splinter Weapon].

Overall, this seems to work for me, but that could be because I haven't done hard enough areas yet.
The major weakness of this build is massive enchantment removal.
So what do you think?

When working optimally, Ether Renewal builds are the most powerful in the game, however, the AI is pretty bad and they don't maintain Ether Renewal as often as they should. If you micro it, it should be fine. The build is destroyed by mass enchantment removal which isn't a huge deal, but is an important weakness. Your EN should probably be a necro, there's just no reason to take it as an EN (And its build is bad). Third build looks solid. I realize the point is to have an unbreakable fortress, but when the enemy does score kill, you have no res.
