Summoning Invocations

[Kuma Kode]

Do they exist? And if so, where? Primarily I was looking for official ones, but homebrewed ones are acceptable.

I'm not looking for power or cheese. I don't care if they summon suck elementals whose only powers are Suck (Ex) and Fail (Sp). I was wanting to make my own summoning-based invoker and if there are official invocations I can base it on, that would be great.

I don't think they exist, though.

Summon Swarm and the Dead Walk are in CArc, those should give you an idea.

Summon Swarm is devastating at low levels, when few if any enemies have the ability to cope against them.

I'd also look into the Binder if I were you. The "Zceryll" Vestige gets pretty much at-will summoning (every 5 rounds, but that's the only limit). Depending on your concept, that might fit far more accurately.

I'm sure it's not very helpful, but I feel I may as well mention the Steal Summoning invocation in Complete Mage.

And as a Warlock you can always UMD wands. Standard Summon Monster 1/2 in this case would have too short a duration, unless you get high level 3/4 wands, in which case it quickly gets overly expensive.

So I would probably just get a couple of Eternal Wands of Mount. They are individually cheap, casts 2x per day, each time giving you a horse for 2 hours. They can't really fight, but you can ride them or send them ahead to trigger traps.
