Improved Natural Attack

[General]
Prerequisite

Natural weapon, base attack bonus +4.

Benefit

Choose one of the creature’s natural attack forms. The damage for this natural weapon increases by one step, as if the creature’s size had increased by one category: 1d2, 1d3, 1d4, 1d6, 1d8, 2d6, 3d6, 4d6, 6d6, 8d6, 12d6.

A weapon or attack that deals 1d10 points of damage increases as follows: 1d10, 2d8, 3d8, 4d8, 6d8, 8d8, 12d8.

This feat may be taken multiple times, but each time it applies to a different natural attack.
