Luckily the SRD is online, so you don't need your books.Larry Fitz said:I was under the impression that the various Summon Monster spells did this but that Gate, because it allows much more powerful creatures to step through, did not actually compel them to do something they wouldn't ordinarily do? That is you have to attempt to Gate in a creature from a plane that would actually want to do the thing you wanted done, or at least be willing to bargain to do so.... I could be wrong in 3E on this, as I said, I don't have it in front of me...

Gate allows you to call and command a single creature with HD up to twice your caster level for up to 1 round/level. It can do other stuff, too, and has a casting time of 1 action. Makes Summon Monster IX kinda worthless, eh?
A dragon of any stripe would have trouble with a few solars. 22 HD, 5 attacks/round with their +5 dancing vorpal swords, cast spells as a 20th level cleric, fire resistance 20, immunity to other energy types except for sonic, 35/+4 DR (and no dragon has better than X/+3 DR), SR 32, wish 1/day, etc. etc.
