On the sidebar for Aasimar it states that a "small" aasimar, such as a Halfling, can be Small but purely for cosmetic purposes. This sounds like a contradiction. If it's purely for cosmetic purposes then why even mention it. If instead it gets Small properties, bonus size AC, chance to hit, 20ft speed, etc. then it's not "purely for cosmetic purposes". Can someone clarify please what the intent is?

How does Keep Watch Spell actually work? It seems like a level 1 spell that can completely eliminate the need for sleep and allow the party to ALWAYS put their best guard on watch every night without the need to make shift changes and have possible ambushes throughout the night.

I am GM'ing a game where a sorcerer has a skunk for a familiar. He wants to take Improved Familiar at level 3 but he wants to keep his skunk rather than simply changing to a new familiar off the new table. I considered using a Celestial/Infernal template. However, I am having trouble finding a good upgrade to make it both worth it to spend a feat on and not overpowered for a familiar. Any suggestions on how to improve it?
