Hitting the ground running off the beaten path

[Graskle, The Rasckle]

I'm new to pathfinder. I barely managed to build a basic character. I want to build a halfling warpriest of the diety Talona
I'm specializing in unarmed strikes hoping to rely on trickery and the standing still meta to get me through combat. The character was intended to be the guy people called when they they are really angry at someone. "I don't want them dead, I want you to ruin their lives." I'm looking for someone to help me make the character NOT hot garbage.

Starting level is 7. I rolled for the starting stats 18, 18, 15, 14, 13, 13.
Help please and thank you.

Talona is a Forgotten Realms CE deity, I might suggest either Mestama a CE deity with Trickery as a domain and punching daggers as her favored weapon. Or Akuma, a LE deity with unarmed strikes as his favored weapon.

If you choose Akuma, you get Improved Unarmed Strike for free at level 1, take your free Weapon Focus for Unarmed Strike at level 1, and use you level 1 feat for Hamatulatsu.

After that, just basic Warpriest stuffs, I suppose. I've never played a Warpriest so I don't have too much advice to give, sorry. But having Hamatulatsu at level 1 is nice.

Buy an Amulet of Mighty Fists, put Cruel and Ominous on it for your unarmed strikes. Critical hits make your target Staggered... Critical with Ominous is Shaken, Cruel turns it to Sickened, Hamatulatsu turns it to Staggered.

Just a thought.
