Vault

 
Prerequisite(s): Jump 4+ ranks, Str 13+.
 
Benefit: When wielding a pole arm two-handed, the DC for a longjump is reduced by-5. In addition, the DC for a high jump is equal to three times the distance to be cleared. If you jump up to grab something, you must drop the pole arm to grab the target.
 
Special: A fighter may select Vault as one of his fighter bonus feats.
