This campaign will be allowing the optional rules system for Stamina and Combat Tricks. The original page for these rules can be found here.
To make use of these rules, your character must have the following Combat Stamina feat, presented here with one small modification:
Combat Stamina (Combat):
You stop at nothing to drive your attack home.
Prerequisite(s): Base attack bonus +1.
Benefit(s): You gain a stamina pool. After you make an attack roll with a manufactured weapon, unarmed strike, or natural weapon attack with which you are proficient, but before the results are revealed, you can spend up to 5 stamina points. If you do, you gain a competence bonus on the attack roll equal to the number of stamina points you spent. If you miss with the attack, the stamina points you spent are still lost.
Special: Since you have a stamina pool, you can spend your stamina points to use any combat tricks associated with combat feats you possess.
Once you obtain this feat, your character will have a Stamina Pool.
When you have an ability that grants you stamina points, you gain a stamina pool with a maximum number of stamina points equal to your base attack bonus + your Constitution modifier. During combat, you can spend stamina points from this pool to perform a combat trick, the specific effects of which are dictated by a combat feat you possess. Spending stamina points in this way is not an action, but you can’t do so if you are unconscious, fatigued, or exhausted. You can use as many combat tricks on the same action or attack as you like (as long as you have the stamina points to spend), but you can’t use the same combat trick twice within its scope. For instance, if you have a combat trick that affects a single attack, you can’t use that combat trick more than once on the same attack.
Dropping to 0 stamina points causes you to become fatigued until you have 1 or more points in your stamina pool.
Temporary increases to your Constitution score, such as those granted by the core barbarian’s rage class feature or bear’s endurance, do not increase the number of stamina points in your pool or your pool’s maximum number of stamina points. However, permanent increases to Constitution, such as the bonus granted by a belt of mighty constitution worn for more than 24 hours, do adjust your stamina points.
You regain stamina points by resting for short periods of time. You don’t have to sleep while resting in this way, but you can’t exert yourself. You stop regaining stamina points if you enter combat; take an action that requires a Strength, Dexterity, or Constitution-based skill check or an ability check tied to one of those ability scores; or take more than one move action or standard action in a round (you can still take free, immediate, and swift actions). This reduction in your number of actions per round also effectively halves your overland speed. For each uninterrupted minute you rest in this way, you regain 1 stamina point.
If you are suffering from any of the following conditions, you can’t regain stamina points:
Confused, cowering, dazed, dead, disabled, exhausted, fascinated, frightened, helpless, nauseated, panicked, paralyzed, petrified, shaken, sickened, staggered, stunned, or battered.
