A quick follow up For Gallows of Madness since the list filled up quickly :)
If you start with a Level 2 character you will not be able to do all three parts with the same character since each one is at least 1.5 XP. The only way to do all three is to have 0,1, or 2 XP on the character to start.
If you start at level two or lower you can go slow for the first two and be level three for part three.
How do you want to deal with accidental splash damage? On a hit I can exclude your square from the damage so that is fine. On a miss I scatter and therefore could do some friendly fire. Pun intended. Do I need to ask permission each time?
