Natural attack penalties

[Korak The Boisterous]

I know the basics so let's skip the primary and secondary rules set, I specically need to know whether or not they take penalties for multiple natural attacks in a full attack action if everything's primary.

[Maezer]

There are no penalties for using primary natural attacks. Not that they are immune to penalties from other sources, just none inherent to making attacks with primary natural weapons.

[Imbicatus]

If you are only making natural attacks, and they are all primary, then they will all be at no penalty and add 1x your str modifier to damage.
