Stamina

This part contains information that applies to 0.D (Danny).

This page is not complete enough; please help if you can.

In 0.D (Danny) there is a stamina level. You slowly regain it over time, and it reduces when you do straining things, like fight, or run (via the " ), or anything else that makes you get out of breath. If you have low stamina, some actions take longer to accomplish. There are various ways to increase or decrease your maximum stamina, such as the Languorous and Indefatigable traits. Other mutations such as extreme metabolism increase the rate at which you regain stamina.

Carrying over your weight limit also causes stamina loss.

Stamina recovers slower the more mouth encumbrance you have.

What is Stamina?

Stamina measures momentary exhaustion from performing strenuous tasks, like running or fighting. It represents loss of breath due to repetitively performing intense, oxygen demanding actions and physical exertion.

Stamina pool

• The stamina pool has 10,000 points; it's one of the hidden stats displayed in game by a set of color-coded depleting bars.
• The stamina pool is affected by traits/mutations: Languorous (-25%), Indefatigable (+25%) and Hyperactive (+40%).

Stamina regeneration

• Stamina regenerates by itself, every turn, unless you have the winded effect.
• Base stamina regeneration is 20 per turn, adjusted by bonuses.
• Expected base time of full recovery is 8.5 minutes.
• Regeneration takes place even on turns when stamina is burned, but some burn mechanics compensate for that.
• Base regeneration is reduced by 1/10 of mouth encumbrance-ergo, you don't want to wear clothing or equipment with high mouth encumbrance when running or fighting.
• Base regeneration is buffed by stimulants and debuffed by depressants.
• Active Oxygenator bionic buffs base regeneration by a factor of 5, at a cost of high power consumption.
• Stamina regeneration ratio is affected by traits/mutations: Fast Metabolism (+10%), Very Fast Metabolism (+30%), Extreme Metabolism (+50%)

Stamina burn

You burn stamina when performing the following actions and activities:

• walking (net positive balance, base stamina burn rate for walking is 15 per 100 moves, so it's possible to regenerate stamina while walking but not as fast as standing in place),
• running (walking burn x7) ,
• melee combat, calculations includes:
  • weapon's weight (malus) divided by strength (bonus), so strength reduces stamina cost for melee attack with heavier weapons,
  • melee skill (bonus),
  • both arms encumbrance (malus),
  • Deft trait (bonus, only when you stumble with attack),
  • minimum burn of 50,
• firing bows (When stamina is low, bow reloading time raises.),
• pulping corpses,
• smashing things,
• using muscle powered vehicles (see below),
• breaking sticks,
• heavy harmful coughing.

• Movement related stamina burn scales up with the depletion of stamina, so at low stamina the burn rate gets higher. Might make walking net negative balance (burn > regen).
• You don't burn stamina when riding an animal.

Stamina in vehicles

In muscle powered vehicles, you are the engine. You will burn stamina according to the "engine" load, i.e. effort you put into pushing the vehicle forward. Load depends on many factors, including speed, drag, efficiency of particular muscle engine etc. All you need to know is that the more you strain, the more you burn. Engine load spikes when you build up your speed, and then sets on a certain level to upkeep that speed. If you keep low speed in relation to that vehicle's max, you will burn much less. If you push it to the max, you will burn your stamina in no time. Some vehicles, like bicycles are more forgiving, and allow net positive stamina balance (regeneration > burn) at low speeds. Other, like kayaks and row boats, need lot of rowing power to move and will burn lot of stamina even at low speeds. Remember that overall weight of the vehicle also matters, including things you keep in the trunk/basket/hull.

• Active Joint Servo bionic significantly reduces stamina burn when using muscle powered vehicles, at the cost of bionic power, but does not affect the speed. It does not affect stamina burn rates while walking and running, but buffs the speed.

When you run out of stamina

• you stop running (if running),
• you get winded effect with certain debuffs.

Miscellaneous interactions

• Both walk and run speed drop to half their maximums as stamina approaches 0.
• Characters attack and throwing speed gets incrementally slower (up to x2 base move cost + encumbrance) when stamina drops below 25% and goes towards 0%. You are out of breath to attack at peak performance.
• Long actions that burn stamina will auto-pause you when you get low on stamina, and make you wait to regain some of it. You will lose some time on auto-waiting, but will have some stamina reserves in case of need.
• You can wait until you catch your breath in the wait menu.
• Military grade stimulants may help you instantly regain stamina and apply extra regeneration during their effects.
• Active Joint Torsion Ratchet bionic significantly increases stamina burn rate when walking and running, producing bionic power in return.
• Chilly/Cold/Freezing as well as Warm/Hot/Scorching effects may apply stamina loss
• Adrenaline Rush will grant extra stamina regeneration while Adrenaline Comedown will reduce stamina regeneration. Also works with its fungal analog.
