Mixing natural and manufactured weapons

[tuesdayscoming]

Alright, so let's say we have a thri-keen character with armor spikes. Thri-keen have 4 claw attacks and a bite. Now, let's say he takes a full-attack.

Does he get to attack with all 5 of his natural weapons (albeit at a -5 penalty), AND the armor spikes, or what? Does the use of the spikes replace another one of his attacks? Or (hopefully not) does it replace all of them?

I can't seem to find the relevant passage on d20srd. I seem to recall that it would work out so that he gets all 6 attacks, but I'm just not sure...

edit: also, how (if at all) would the multiattack feat affect this?

Look in the SRD, under special abilities > Manufactured weapons.

You may make an attack with a manufactured weapon, then as many natural weapons as you possess (unless they are restricted from attacking; for example, claw attacks when you're holding something in the claws).

All natural weapon attacks in this case are secondary weapons. They take a -5 penalty to the attack roll (-2 with multiattack), and only get 1/2 strength to damage.

Bah! Not sure how I missed that.

Thanks, candycorn!
