Lore accurate Templar build?

I was wondering which would be the most lore friendly build for a templar and try its effectiveness.

My guess is that it would be a melee-staff wielder, Armor + Energy Shield equipment with focus on fire/lightning attacks (Smite and Consacrated Path ofc), the holy relic skill and another spell then a friendly aura (don't know if curses applied on hit would be lore friendly too).

Some skills might require a cosmetic purchase.

What would you add/change?
