Is it possible to cast from a wand while in the pit? If so, I use a couple of my wands: Vigor, and Cure Serious Wounds, on Raoul. Unless he's stone-dead.
UMD x2:
1d20(4)+24=28
1d20(16)+24=40Both succeed. Both wands at CL 6.
Vigor last 16 rounds and grants fast healing 2 (so, it heals 32 points over a minute and a half or so);
CSW:
3d8(8,2,8)+6=24 hp healed.
Total is 56 hp, which should get him to full I believe.
If I can't cast while in the pit, or if he's just dead, then Raoul's just screwed for now.
