Improved Multiattack

(Draconomicon, page 70, DnD 3.5)

[Monster]

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

Prerequisite

Multiattack, Three or more natural weapons

Benefit

Your secondary attacks with natural weapons have no penalty on the attack roll. You still add only 1/2 your Strength bonus, if any, to damage dealt.

Normal

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