Hi,
I'm in the process of scaling up the Champion's Belt adventure's encounter with the Alkilith, as per the adventure's sidebar. But I don't have Fiend Folio handy, and the stat block provided desn't appear to include an advancement entry - does anyone know if adding 4HD to an 11HD Alkilith would cause it to increase in size? I would imagine I'm not the first one to run a 10th level party through this adventure, so hopefully some of you have had occasion to look this up before and can remember without having to go find your copies of FF... but it's apparently on page 46, just to make life a little easier on anyone who is nice enough to look it up, in the event nobody remembers its new size category off-hand.
The base demon is Medium, so I'm guessing it will end up as Large, but I'd like to know for sure before I guess wrong and do all that work for nothing. Not that they aren't just as likely to all get swallowed to death by an advanced Madtooth the Hungry before that ever happens... But they do tend to get unexpectedly lucky sometimes, so who knows?
Thanks,
Kang
