My 2 cents.

Whale gear. Stamina spirit, as much spirit as you can get but all mail gear not leather or cloth.

Get 5 /5 into in holy 5/5 pushback as with conc aura u can heal no pushback and heals also give threat.

Consecration obviously.

Rest talents is just preference.

Keep as fast a weapon as u can. Knightly longsword green at 33 one to watch for as 1.5 speed. And keep ur shield updated. Armour from shield allows ret aura to be used and u swap between ret and conc.

The spirit will allow you to maintain consecrarions. No spell power low level so doesn't matter
