Buffer build advice

Hey everyone,

so I want to make a proper buffer build as templar, what do you think about this build?

They told me to go very much deep on defence and aureas bonuses so here what I came up with, maybe I can replace mace damage with some Lightning spell damage (don't know yet if I will go melee or caster, probably caster) and make a build on lightning spell, is a good choice for partying at high level? Is gonna be pain to level this up right?

I've not seen any build on the web, just wanted to build one on my own.

Specs:

Shield + mace or shield + anything and high armor, spell build undefined :p

Cheers^^

Ok...I was joking, I've made a final and proper one^^
