Cha 14 sounds right.
What if we up the CL to 10 and give it Quicken SLA? (I'm still smarting from Paizo developer comments about Ability Focus.)
Plain old shortsword and shortbow?
That seems a bit much. If you're opposed to Ability Focus, let's at least go with a racial bonus. It's their one schtick.![]()
I'm on-board with shortsword, but the bow feels "too martial" for these charmers. How about a light crossbow?
CR 1 or 2.
Treasure sounds right.
I'd go 3-4 HD (Medium), 6-8 HD (Large).
Jello's mostly water, like people, so 175-200 lb?
I'd like both single-type and mixed-type groupings of 2-8 or 12, but I don't have a good idea for a name!
