I always say, "play what you like; we'll figure it out."
If Belkregos or Hoondatha want to adjust their character stats, and Hedge allows it, and they WANT to play a multiclass cleric (I have to say, one of the more interesting builds I've seen lately is
Garth, from Adventures in Foxmoor, who is an elven mage/druid. Hit points average a bit low, and progression is going to be slow (4500 xp to get both classes to 1st level), but... with WIS bonuses, he starts out with five spells at first level. And he can wield some weapons, even ranging with a sling if need be. The only real drawback is that he won't have healing spells until he can cast 2nd level druid spells.
Anyway... I thought it was interesting.
I think I agree with AQuebman on this one, though. We have a PC-turned-NPC healer. Let's just hold on to him. If someone ever wants to join the game, we have a character for them to take over. Otherwise, we're not messing with the cohesion of the party and we still get our heals.
But potions and scrolls and magic items are still welcomed!
Dragon foot. Bamboo pole. Little mouse. Tiny boy.
