(For people playing in my game at Fort Fritz... go away!)
Alternative BBEG for rivers run red:
Same gear, same size, same feats, but smart, better armored (from the templates dex and natural armor), magical abilities (including flight), and spell resistent. Most importantly, intelligent, which will vastly increase his lethality. Hits less often, but for more damage.
The best part: same CR!
In the case of the Fey Dire Bear (needs a name, doesn't he/she?), the increased intelligence can be used for hit and run tactics, singling out dangerous opponents (the evoker, in my group), etc.
My hands are rubbing with glee...
Anyways, here is the link:

I wonder if I'll give the Owlbear the Fey template instead.
Though this idea looks good too, so I'm taking it into consideration.
According to the "rules", you can only apply the template to animals. But feel free... it's your world.
I'm considering taking off the armor, since I'm not sure my party can reliably hit the AC... on the other hand, I can buff them up with NPC's. I really want this thing to make them shiver in their boots.
Death curse is a -2 to all d20 rolls until removed; goes off on the creature that slays the beast and paints an angry red halo that only fey can see.
