Improved Multiattack

(Savage Species, page 36, DnD 3.0)

[General]

You are particularly adept at using all your natural weapons at once.

Prerequisite

Multiattack, Three natural weapons

Benefit

The usual -5 penalty on attack rolls for secondary attacks does not apply to your secondary attacks with natural weapons. The damage bonus for such attacks is still only 1/2 your Strength bonus, if any.

Normal

Without this feat, your secondary natural attacks take a -5 penalty (or a -2 penalty if you have the Multiattack feat).
