I need to create an 11th level character. For story reasons, I need to be a warpriest or a cleric (catfolk). Wandering if its better to multiclass the warpriest after 10th, or stay pure warpriest. Since he receives his major blessing at 10th, is there anything worth attaining afterwards? What class would blend best with the warpriest?
1. Quicken Blessing
2. More Fervor.
3. More spells, including more scoops of Divine Power and Righteous Might.
4. More full BAB Fighter feats to pick up beauties like Pin Down or Spellbreaker.
5. More scaling on Sacred Weapon/Armor.
since your saying your options are warpriest 11 or warpriest 10/ X 1 I suggest going bloodrager at your 1. Take the extra rage feat sometime and you have enough rage for a normal day. Take it as your first level and get extra HP. And if you're interested in this option I have 2 particularly effective versions that I can explain more of to make it better and I can explain more as to why I feel this synergizes well too if requested.
How awesome it is is effected by how fast level ups are and expected ending level.
slayer/warpriest
dual wield kukri
be an asamar

wep focus the wings

Have you considered Holy vindicator? For that matter you may want to rethink and go Cleric (Archtype that gives +2 CL) and then holy vindicator
