Weird stuff[]
I summoned one of those in the Mephit Portals room in Irenicus Dungeon using the scroll I found earlier. After destroying the portals I quicksaved and quit the game.
First of all, when I loaded the game again the elemental became hostile and attacked the party. I killed it, but reloaded 3 more times until it finally stayed friendly to us.
When we proceeded towards the room with the wand-traps I had the elemental in front of the party, and my jaw dropped when I saw that it sprang the trap (and took damage, disarming it in the process) before the door to that room. But it could also activate the wand-traps, once we got inside (and was killed by one). Well, I thought summoned creatures can't do that...
