It's pretty widely thought that the Summon Monster I-IX spells are underpowered, especially on the lower end. I have personally found that to be true, and never really tested them at the medium to high levels. Today I finally decided to do some mathematical analysis on the CRs and whatnot of the various creatures summonable; here are my results:
None of the CRs here take into account templates added to the applicable creatures.
Summon Monster I: CR 0-CR1/2 creatures
2: CR 1/2-CR 1 creatures
3: CR 2 creatures
4: CR 3 creatures, with a few lower but with spells
5: CR 3-CR 5
6: CR 5 -CR 7, with the Unicorn at CR 3 and the ability to heal
7: CR 7 -CR 9, with a few lower
8: CR up to 10, with a bunch below 7
9: CR up to 13 (with one CR 14), with Xill at 6 on the low end
All said, these CRs are woefully low, especially when fighting other monsters. The only thing I can find worth using are the big dire animals, and a few stuff with good utility spells (none have good offensive spells). Most of the non combat utility goes out the window due to the low duration.
With some simple brainstorming, here's some ideas to fix the summons:
A. Extend the duration to 1 minute per level.
B. Give a d3 of summoned monsters at their level, and double it for each step lower on the list.
C. Allow a caster to use a higher list, but decrease the duration to 1 round/level.
D. Allow the caster to use a list two higher, but make the duration into concentration.
E. Something else?
What do you guys think?
