Stamina Adherent (Legendary Fighter Archetype)

Fighting Stamina (Ex)
The stamina adherent gains a stamina pool with a maximum number of stamina points equal to his fighter level + his Constitution modifier. The stamina adherent can spend stamina points to use any combat tricks associated with combat feats he possesses. If the stamina adherent gains the Combat Stamina feat, he also gains the Extra Stamina feat as a bonus feat, even if he doesn’t meet that feat’s prerequisites. Gaining the Combat Stamina feat doesn’t grant the fighter second stamina pool, but does grant him the benefits of that feat and allows him to use his total HD + Constitution modifier to determine the size of his stamina pool. A stamina adherent chooses two less skills than normal to become class skills with the bonus skills class feature.

This ability modifies bonus skills.
