Stamina(stat)

Stamina (STA) is a minor attribute in AdVarTa, representing the physical disposition and energy to perform actions or labors. It's dependant on Toughness and some multipliers.

Like the attribute Resolve, Stamina is subdivided in Maximum Stamina and Current Stamina, as it may be lowered by actions, injuries, and many other things that could produce pain or tiredness. As such, Stamina is the primary element in AdVarTa's combat system, limiting almost every ability of a character during combat and other actions. Compared to other systems, Stamina is like Hit Points, but not stupid.

Beware, as Stamina is one of the mechanical monsters of AdVarTa, with much more rules than most other RPGs.

Current and Maximum Stamina
There's no secret here. Current Stamina is, basically, the condition of exhaustion of a character while Maximum Stamina is the highest value the Current Stamina of a character can naturally be.

In other words, Maximum Stamina is a static value calculated as double the Toughness plus any kind of bonus.

The real deal, though, is the Current Stamina. It is what the system actually uses when determining rolls and such. When the Current Stamina has positive value, the character can fight or work at full capacity. When it drops below 0, fractions of its value are added to the statistics Block Rate, Control, Evasion, Hit Rate and penalize most skill checks. Everything that is affected by your stamina only gets worse when you spend your 'surplus' stamina.

Effects
As explained before, Current Stamina is what you'll be actually using, while Maximum Stamina is more of a Character Creation statistic.

So, the net Maximum Stamina shall be understood as a margin where a creature can work efficiently (or a surplus/range).

This leaves Current Stamina as the determining statistic for whatever penalties occur as combat or other tiresome activities progress.
 * Block and Evasion are reduced by 1 for every -5 Stamina.
 * Hit decreases by 1 for every -10 Stamina, to a minimum of 1.
 * Every -10 mark you reach reduces your Maximum Stamina by 5 until extended rest.
 * If a character's Current Stamina is at a negative value equal to 5 times its Toughness, it's close to passing out.

Modifying Current Stamina
A lot of things can decrease one's Current Stamina.

The following table contains some examples:
 * Taking a break can replenish Current Stamina at a rate of 5 per minute.

In the Combat Section (and a bit in the Skill Checks), all the Interactions of Stamina are further explained.
