Question 1)
If a level 15 (or level 11 with Robe of Arcane Heritage) Sorcerer with the Abyssal bloodline Summoned 1 Demon, his Added Summonings would add one to that. Would that then activate the Superior Summoning feat?
I can see both ways. He cast a summoning spell, and two creatures were summoned. However, one could argue that it wasn't the spell that summoned the second creature, but the class feature.
...then again, one could argue that the class feature augments his summoning spells, so it was the spell.
So, I dunno.
Question 2)
I never thought about this way until someone pointed it out, but if you summon 1d3 creatures from a lower list, Superior Summoning only activates if you roll a 2+. That's how I always took it. They thought that 1d3 would be more than 1, so it would always activate. I'm pretty sure my understanding is more accurate, but wanted to hear what you think.
Question 3)
Similiar to question 1, but not exactly: If one cast a summoning spell, bringing out 1d3 creatures, but also used a cauldron of overwhelming allies, does this guarantee that Superior Summoning would kick off? Or, if I roll a 1 on the spell, does Superior Summoning just not kick off, even though I'll still be getting at least one more creature summoned?
On this one, I'm leaning more towards it doesn't automatically pop Superior Summoning. The wording of the item ("...the cauldron automatically conjures 1d3...") makes it kinda clear that this does not augment the original spell, but just uses an ability alongside a spell. But, again, just looking for input.
1) Yes, the Superior Summoning feat would be activated. The class feature does not summon the creature -- if it did, the creature would be undispellable as the ability is a Su. Moreover, the ability cannot summon anything by itself. It augments the spell.
2) The phrase "a summoning spell that conjures more than one creature" can mean a summoning spell that has the capability to summon more than one creature". So, using a spell that has the ability to summon more than one creature always triggers superior summoning regardless of the number rolled on the die.
3) As the item is used as a focus for a monster summoning spell, this would work to trigger superior summoning, however, you would only get an additional monster off the lower level list, as long as the spell you used only has the ability to conjure a single monster.

1) I'm inclined to agree.
2) Again, I can see both ways. It would be simpler with your reasoning, and I may go with it because of this. But if you roll a 1 on the die, the spell did not summon more than one creature, technically.
3) It is used as a focus, that's true. So I would argue that it augments the spell, as well. And I agree, Superior Summoning would give you the 1d3 creatures, not the single. If that makes sense. Mostly, I was thinking if 2) would mean 1d3 doesn't always pop off Superior Summoning, would adding this item guarantee it. But, I'll probably say that 2) does always pop it off, so this question isn't as relevant anymore.
it is quite commonly agreed that the feat triggers on options that can summon more, regardless of if you actually did.
Cool deal.
