Valueing a "Summon" ability in CR


Advice


Wondering what folks consider a "summon" ability to be worth on CR; I have a creature summoning 1d3+1 CR3 creatures; the base shell was a CR4 5HD creature that's gotten that tacked on without much else.
As is, by XP values, that's a CR 7-8 encounter at with 4 summoned creatures, 6-7 with 2 summoned creatures. Should the summoning creature get a bump in CR itself?

The ability to summon creatures is already taken into account with the main creatures CR. No need for adjustments and no XP is awarded for killing the summoned creatures. Also remember that summoned creatures cannot use their summon ability, so there won't be a cascade of monsters.

Actually on this one I'm ADDING the ability to summon to something that normally doesn't, so its not really built into the CR calculations; that's the math I'm attempting to do.

Is there a chance the summon might fail like it is with some outsiders, or is it automatically successful?

Auto-Successful, round delayed. I aped the Vampire's "Children of the Night" for the general build. Summon Nature's Ally, the closest spell for these purposes, is a 4th level spell, castable at 7th level, so a CR 6 NPC can summon the same.

Using the Vampire as the template again, they get a whole host of abilities (and some weaknesses) at a CR+2 boost; I was thinking a +1 to CR (my main creature then would be a CR 5) would do the trick but I want to check my math with others before settling.

Ah, if you're creating a creature... +1 is probably appropriate. Maybe +2 if they can do it multiple times per day with no failure, and in the same round, like most daemons.
