Cleric Qlippoth Summoner

I was thinking of making a CN human cleric of Rovagug in PFS who specialized in summoning, and thought qlippoths would make for some interesting minions. Not sure about specifics though. Herald Caller? Evangelist? Something else? Any build advice?

Even with Expanded Summon Monster there's only a couple of qlippoths you can summon in the usual PFS level range - the cythnigot at SM III which is an improved familiar option and the shoggti at SM VI. Both of them have horrific appearance which would affect your allies, I've read that such things are a no-no in PFS. i.e. you will need to summon other stuff too.

I like the herald caller because of the skill points alone. The evangelist summoning demons and qlippoths is faced with a choice between inspiring courage in their summons or in their party, unless the party members understand Abyssal, which seems to devalue that ability a little.

Aside from making sure you get augment summoning (automatic for the herald caller) and sacred summons, I'd suggest the lightning subdomain. The low-level spells are useful before the summons get going and the high level ones are no slouches either.

also summoning evil things makes the spell evil and is such an evil act - also not allowed in PFS I think

For better or worse they ignore that in PFS, you can spam Evil spells all day long and not worry about Alignment shifts.

A small reason I don't care for PFS but given the ever changing setup of GMs and players I can see why they do that.

Well, that is disappointing. Oh well, thanks for the advice.
