Improved Multiattack
( Draconomicon, p. 70)[Monster]
You are particularly adept at using all your natural weapons at once.
Prerequisite
Multiattack (MM2) , 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).
