Yes, I know how magic missile works. To save the arguments (which I had been anticipating) about whether or not my friendly imp gains full cover or not. The imp flies under the table and you lose sight of him by the table blocking him out. (If you want to argue with me about whether or not the table would block him out, please feel free to email me something exciting with trigonometry). For those who have seen the imp previously, you know he's hiding somewhere in the vicinity of the table as that's where he flew and I’ll give you + something (+6?) I haven’t decided yet on the spot. If you have strong feelings about what this plus should be or about anything else, email me and we'll work it out offline.
Amaryllis. You’ve been hiding behind the door, concentrating on your spell on Runor. You have never seen the imp. You may have heard a high pitched voice (roll if you want to), but you don’t know what type of creature it came from or where it was. If you choose to cease hiding behind the door and walk out into the middle of the room then you can try and find a creature to match the voice. To save time I rolled for you … you don’t see him, he’s hiding. He’s really good at hiding.
Still Amaryllis: Do you know about Namfoodle’s spell. Okay, you’ve been concentrating and listening for Runor/Seebor. To identify a spell is normally DC15. However, since you didn’t roll concentration checks for the your spell to indicate that you weren’t paying almost full attention to your own spell, I think it would be extra hard for you to have picked up on Namfoodle’s spell. As a random thing I’m going to make it DC19. Please note, I did this prior to going back and looking up what you rolled on your spellcraft check. If anyone has a more scientific method of determining if someone could identify a spell whilst they’re concentrating on their own let me know and I’m more than happy to alter this decision. Maybe I should have made you roll a listen check. Not sure. Either way you didn’t hear Neblin’s spell.
General query: Does the DM always feel like the general spoilsport, or am I just special?
