Nightscale
Nightscale's breath weapon is rather puny, IIRC. 4d4 or 6d4 acid damage, I think, with a reflex save. On the other hand, she's terrifying to a 4th level party in melee. When I ran FoF, one of her goals was to bull rush a character in heavy armor off the bridge into the river, but I failed
If you want to make her tough:
- her first attack should be a bull rush from the water into a character on the bridge, back into the water. Even if the character isn't heavily encumbered, they're out-of-sorts in the water. IMC, most PCs have lousy swim scores.
- try to isolate for a full attack on any character, but preferably an unarmoured one. If they look lightly armored, use power attack for 2-4 points.
- once she gets wounded to 50%, she can retreat to the water and hit them with breath attacks, concentrating on anyone throwing offensive spells or good archers.
- once she gets badly wounded, have her flee. Nightscale's young, but she's not stupid, nor is she as arrogant as big U. I had her grab what treasure she could carry and run away. When the group finally went down underwater with some water breathing potions, they were most displeased to find naught but a couple thousand silver pieces
