I am playing a game where the DM has ruled that conjuration (summoning) is more similar to conjuration (calling).
Specifically what is happening is that the manifestation of what I am summoning is a specific creature that will remember past summonings. So when I send a summon down a corridor that I am pretty sure is trapped, if they set it off and are injured, they will remember it (including, if I talked to the party about it, that I knew it was trapped) every time I summon them.
I showed him a related question and was given the following response:
You nave the raw right in the magic rules right here, I have no idea what James Jacobs is talking about.
Summoning: A summoning spell instantly brings a creature or object to a place you designate. When the spell ends or is dispelled, a summoned creature is instantly sent back to where it came from, but a summoned object is not sent back unless the spell description specifically indicates this. A summoned creature also goes away if it is killed or if its hit points drop to 0 or lower, but it is not really dead. It takes 24 hours for the creature to reform, during which time it can't be summoned again.
The reason he has done this is because of commentary in the invisible stalkers block.
Over time, or in the service of a particularly vile master, invisible stalkers form negative opinions of these creatures of flesh and bone, leading to their tendency to pervert their instructions and cause harm to their masters. For older and more experienced invisible stalkers, the only thing protecting those who summon them is the magic that binds them. These creatures automatically try to use inconsistencies in the wording of their tasks and literal twists on the intention to find a way to inconvenience, injure, or even kill the priest or arcanist that brought them to the plane.
And some wording under the description of conjuration
When the spell ends or is dispelled, a summoned creature is instantly sent back to where it came from.
A summoned creature also goes away if it is killed or if its hit points drop to 0 or lower, but it is not really dead. It takes 24 hours for the creature to reform, during which time it can't be summoned again.
I have an ability which allows me to keep my higher level summons for a very long time, at least all day. So with this increased amount of usage, I fear that I am going to start having problems with my common summons in the near future.
How can I work with my summons under these conditions? If I can't risk my summons to prevent risk to myself, then I'm not sure why I'd bother summoning them. I don't want to need to have very carefully worded commands for everything.
