You know how to alter your grip on a Spiked chain or similar weapon to use it against opponents at reach.
Benefit: When wielding a spiked chain or similar weapon that you are proficient with, you may treat the weapon as if it has reach. The weapon is unwieldy when used in this fashion and you take a -2 penalty on attack rolls when attacking an opponent you normally could not.
Normal: Spiked chains cannot be used at reach.
Special: Since most of the chain is now utilized for reach you may not benefit from any other Spiked Chain feat such as Cornugon Shield.
A fighter may select Reaching Blow as one of his fighter bonus feats.
