ooc: About the baby sitting issue, I really don't expect any for my character, at least no more than it's the normal for a wizard-type character anyway. I choose to put my 1st level character in an adventure for 3rd levels, which means that the risks are great for him. If he dies, well, I'm not that attached to him, and he could also have leveled very quickly. And I'm not so selfish that I expect the other players to spoil their fun for a decision no one forced me to take.
About the pay, we could also make the high levels have a greater part of it, though the point is IMO right now moot. We can use the front pay to buy the wand and some healing potins, should Ristyl's character (the one that can use the wand) fall unconscious, then discuss at the end or after the adventure how to deal with treasure.
