Powerful Charge
(Eberron Campaign Setting, page 57, DnD 3.5)
[General]
You can charge with extra force.
Prerequisite
Medium or larger size, base attack bonus +1
Benefit
When you charge, if your melee attack hits, you deal an extra 1d8 points of damage (if you are Medium size). For Large creatures, the extra damage is 2d6; for Huge, 3d6; for Gargantuan, 4d6; and for Colossal, 6d6. This feat only works when you make a charge. It does not work when you are mounted. If you have the ability to make multiple attacks after a charge, you may only apply this extra damage to one of those attacks.
Special
A fighter may select Powerful Charge as one of his fighter bonus feats.
