I have heard IG that using summons to set off traps is illegal, or at the very least, frowned upon. Could someone clarify the DMs' position on this?

You should be after an IC answer to an IC question!

Yes. Thank you, Snoteye. What do you think of it? When I said, "IG", I meant tells and things, not IC interaction.

There's a summoning item in-game named 'The De-Trapper 2000'. We don't mind it, but I don't think clerics of animal-associated or goodly deities would look favourably on the act of causing a summoned creature undue pain.
