Cast From Stamina

Stamina is usually used for physical activities. However, in some settings, it also fuels spells.

If there are other systems of magic in the setting, casting from Stamina usually has these characteristics:
  1. You get lower total power than in a Mana Meter; either spells have a lower power level, or they run out quickly.
  2. Stamina regenerates much quicker than Mana; compared to a normal mage, a Stamina-based caster can cast many more spells per day, and with proper resource management, they can outlast one in battle.
  3. Exhausting your spell power will also leave you physically exhausted and unable to run.

Often overlaps with Cast from Calories; Expect this kind of mage to be a Big Eater. As a consequence of Stamina being a vital spellcasting stat rather than a Dump Stat, Magic users in this paradigm tends to be much buffer than your average Squishy Wizard.

Compare and contrast with Cast from Hit Points, which wounds the character, may be lethal if done to excess, and is usually associated with Blood Magic and The Dark Arts - but which is generally more powerful than casting from stamina or mana, due to the higher risk involved. Many works include both, though, Cast from Hit Points being the Dangerous Forbidden Technique version.


Examples:

Literature
  • Magic users in Eragon expend as much energy when performing a task by magic as they would doing the same task by conventional means.
  • In The Belgariad sorcery is exhausting. Beldin teleports a bunch of loose rocks from a riverbed into a pile to use as building material for a tower and it's all he can do to walk the next day.
  • In The Kane Chronicles, magic works like this.
  • The Diadem series uses this: the protagonists often drain every ounce of magic in spells by the end of each book's climax, but only require a day or two to recover to be back to full strength.
  • In The Wheel of Time, channeling the One Power in large amounts or for long periods of time is as draining as intense or prolonged exercise. Channelers providing backup in a protracted battle work in shifts so they can rest, while some push through and drain themselves to the point that they can barely stand. Channeling past the point of exhaustion is particularly dangerous because it can cause a Heroic R.R.O.D. and sometimes a permanent De-Power.

  • GURPS. Fatigue is measured by loss of Strength points. If Strength reaches zero, the character falls unconscious. When a mage casts magic spells, each spell cast drains a certain amount of either Health or Strength (Fatigue). The more spells you cast, the weaker you get.
    • One of the first spells an apprentice will usually learn is "Aid", which allows him (among other applications) to transfer his Strength to someone else. This allows his master to cast spells that would otherwise cost to much for him to cast, and is one of the major reasons wizards take apprentices.
  • Dungeons & Dragons. In early editions of Advanced D&D casting some spells costs points of Constitution. For example, casting the Identify spell lowered Constitution by eight points. The DM could require a character to make a Constitution check, and failing the check meant the character would become fatigued and have to rest.
  • Hero System: Casting spells or using other powers normally uses up points of Endurance. They come back rapidly with rest, though.
  • In Ars Magica, it can fatigue a mage to try casting a spell that's beyond their skill to use safely, or to improvise all but the weakest magical effects. This can be shaken off within minutes or hours, but Ritual Magic invariably takes bed rest to recover from, and can roll over into Cast from Hit Points if the mage isn't strong enough.
  • In Shadowrun mages have to roll to resist Drain when casting spells. If the spell's Force is lower than their Magic attribute they take stun damage, or fatigue, on a failed resist. Spells with greater Force are another story.

Video Games
  • Rogues in World of Warcraft use stamina.
  • Magical Battle Arena has a Sprint Meter that doubles as a Mana Meter for your normal ranged attack. When Fate switches to her Sonic Form, not only does her speed increase, but her Sprint Meter's rate of consumption while dashing drastically decreases as well.
  • Vindictus has the stamina meter goes down when you sprint, pick up heavy stuff, use magic as Evie, block attacks as Fiona, or use smash attacks.
  • Evil Islands: Curse of the Lost Soul combined the Sprint Meter with the Mana Meter: it was depleted by either spellcasting or running, and it only replenished when the character was motionless.
  • Arcanum: Of Steamworks & Magick Obscura had separate meters for Hit Points and Fatigue. The latter would run down when running, fighting, heavily encumbered or casting spells, justifying the Robe and Wizard Hat since robes were among the lightest non-technological apparel in the game.
  • Betrayal at Krondor mixes this with a Cast From Hitpoints mechanic. All characters have a certain amount of Health and stamina, with stamina being lost before health. Stamina acts as a free hitpoint reserve, however, skills and abilities degrade as health is lost. Mages use health & stamina to cast spells, switching to Cast From Hitpoints, which lowers their own abilities, when they run out of stamina to cast.
  • Betrayal in Antara, being the Spiritual Successor of Betrayal at Krondor, has a similar system of stamina and health points, with mages casting from stamina until they are forced to switch to Cast From Hitpoints. However, the game goes a step further by making in-battle healing via resting or magic healing only restore stamina, not health.
  • Using magic in Dark Souls costs stamina, in addition to using limited casts/FP, from Dark Souls II onward.
  • The Saga of Ryzom allows you to customize your spells in a way that allows this, which gives you more points to do things like shorten your recast time.
  • In Dragontorc on the ZX Spectrum, the magic system is Vancian; but some spells, such as bane, continue running until deliberately stopped. While they're running the player's stamina is gradually drained.

  • In the fictional MMORPG Insania Online every class can choose between Mana, Rage and Energy at character creation (Energy being a Stamina analogue, in that it's a small resource pool that refills quickly), leading to some odd possibilities like Rage-based healers or Mana-based warriors.
