Spell Perfection and Summoning Feats

[Oserath]

In addition, if you have other feats which allow you to apply a set numerical bonus to any aspect of this spell (such as Spell Focus, Spell Penetration, Weapon Focus [ray], and so on), double the bonus granted by that feat when applied to this spell.

How would this interact with Augment Summoning and Superior Summoning? Would creatures come with +8 Str and Con, and would you get 2 extra creatures whenever you summon more than one at a time?

[Drachasor]

Yes, all those would double, as they provide a set numerical bonus to an aspect of the spell.

[Buri]

Be careful as spell perfection only applies to a single spell. That is either summon monster I OR summon monster III, for instance. It doesn't apply to both. Don't think this "breaks" the master summoner.

[Oserath]

I don't think it breaks anything. I do think that a lvl 15 Abyssal sorcerer who can summon 4 creatures off the SM7 list is pretty potent, possibly worth waiting til an even higher SM.

Now, taking it with SM IX would be pretty awesome.
