This is a little build that I tried out and worked rather good
E/Mo
10 smiting
8 energy storage +1 headgear +1-3 from rune
12 Protection Prayers
Skills:
Aegis
Reversal of Fortune
Shielding hands
Protecting Spirit
Baltazhaars Spirit
Aura of restoration
Zealots Fire
Ether renewal (Elite)
Always when you use ether renewal, have as many enchantments on you as possible for maximum effect.
Watch out for getting less than 20 energy, because you want to be able to use ether renewal +some other low energy spell as reversal or shielding hands.
Aim for as much energy as possible.
enchantment removers and shutdown/interupt/energy denial mesmers are this builds worst enemy.
