So I've been checking out the various summoning handbooks(Practical Demonkeeping, Mastering the Malconvoker, etc), but there's a couple ideas I've had that I haven't seen in those threads, and some questions I wanted to ask. Basically, I'm hoping to see if we can't come up with some new summoning tricks that haven't been mentioned yet, both in 3.5 and Pathfinder.
Some things that come to mind:
1. Am I correct in thinking that taking both the Southern Magician and Initiate of Obud-Hai feat(edit correction: first from FR and second from Dragon) can allow a Wizard to spontaneously cast Summon Nature's Ally spells(which further allows for Greenbound Summoning and other like feats)?
2. Malconvoker trick the 1st: Celestial summons getting Malconvoker summon benefits. Corrupt Summons feat(Dragon) plus Celestial Summoning Specialist(Planar Handbook). Celestials are already outsiders. Corrupt Summons makes them evil(by giving them the evil subtype), which means they qualify for Malconvoker goodies like Infernal Horde etc. could this also be applied to Planar Binding?
3. Malconvoker trick the 2nd: the Pathfinder Feat from UM called Superior Summoning should work with Infernal Horde, correct? Which means 3 critters instead of 2.
4. I've been speculating if there would be any way to get Infernal Horde to work with elementals, perhaps with using #1 as a starting point. But first, I don't think elementals qualify as outsiders always, and secondly, IIRC, Malconvoker specifies using Summon Monster with most of its abilities.
