No, I didn't come up with a visual for where the PCs and NPCs are standing. I just eyeballed it in my head. I admit I forgot about the summoned elemental, but I don't think it would be in the blast range. When Brutus jumped he likely would have come down either next to the elemental (on it's right) or in front of it.
Thinking about it more, both Timmins and Maur might be on the edge of the blast (and not actually in the range), which is 5 feet around the spot where Wieland in standing. The cultist is definitely in the range and so is Brutus.
Anyway, I'm just letting you guys know I'll be away from my PC for the next couple of day. I have to go over to my mom's and help her with some stuff. The apartment has been sweltering this week and I need to spend at least one or two days sleeping in her house's basement in order to feel normal again.
I'll probably be home by late Sunday but it could also be early Monday by the time I get home. I haven't decided yet.
