Homebrew monster. Looking for constructive critique

I think this will work better, yep. I'd initially hoped it would work by expanding the Quasit's progression more or less by the book, by speculating that there are larger ones out there. But the Quasit hogs tiny to 6hd, inflating the power larger sized quasits beyond what I'm looking for. Also, it really doesn't matter

Yes, I think that'd work better.

I make out it'd result in the following changes:

Moon Demon
Small Outsider (Chaotic, Extraplanar, Evil)
HD 4d8 (18 hp)
Speed 20 ft. (4 squares); Fly 50 ft. (average)
Init: +6
AC 17 (+1 size, +3 Dex, +3 natural); touch 14; flat-footed 14
BAB +4; Grp +0
Attack claw +8 melee (1d4 plus poison)
Full-Attack 2 claws +8 melee (1d4 plus poison) and bite +6 melee (1d6 plus 1d6 acid)
Special Attacks Poison, swarmfighting
Special Qualities damage reduction 5/magic or cold iron, dark vision 60 ft., fast healing 2, immunity to poison, resistance to fire 10
Saves Fort +4 Ref +7 Will +5
Abilities Str 10, Dex 17, Con 10, Int 8, Wis 12, Cha 11
Skills Bluff +7, Diplomacy +6, Disguise +0 (+2 acting), Hide +14, Intimidate +5, Listen +8, Move Silently +10, Search +6, Spot +8
Feats Improved Initiative, Weapon Finesse (B), Multiattack
Challenge Rating 3

Looks good to me. Reflects what I had in mind very nicely. Very happy with that, thanks for your help!

Glad to be of help.

Looking at my previous post, I notice it's still got a few minor formatting errors - e.g. missing spaces, the "Weapon finesse" needs a capitalized Finesse and the skill numbers ought to have plusses before them.

Might as well fix 'em.
