Mana is the concept of magical energy in InnWorld. It is inherent to all beings, but not everyone can spend it through magic. Mana can be released as a raw energy, ready for anyone to use it with Magic - that is the concept of free mana.
Generating Mana[edit | edit source]
Each living thing can generate mana, but the amounts are wildly different. Toren is able to sense the amount of mana in people, and he found that Ryoka produced four times the amount of raw mana that Erin produced, and Erin produced just enough to keep Toren alive. [Mages] like Pisces or Ceria were able to easily sustain 10 skeletons like Toren.[1]
Sage's Grass is a plant species that generates more Mana than many others. The large quantities of mana available through Sage's Grass can attract monsters or even create monstrous animals.[2]
Mana Reservoirs[edit | edit source]
There are certain places that supernaturally accumulate free mana, especially dungeons. This attracts monsters to inhabit them, as they are drawn towards magical places. The mana of dungeons allows "regular" monsters to grow larger and more dangerous; and some monsters and undead can't even exist without constant mana supply like that of a dungeon.
Battlegrounds are another important place where free mana lingers; which is the reason that undead appear after a battle.
The skill [Magical Grounds] allows magic in The Wandering Inn to work more effortlessly, which means that the Inn also serves as a mana leyline. It powers, among other things, Erin's Magical Door.[3] Other magical artifacts on the inn's grounds that either consume or produce more ambient mana include the magical chessboard, the faerie flowers, the Sage's grass and various [Mages] and [Druids] living on the premises.
Mana Stones[edit | edit source]
Magical energy can be stored in Mana Stones (similar to electrical batteries) or Magical Gems. Mages can load these stones with raw mana, which is considered an exhausting activity, but allows them to store their mana to later access it or to give it away. Such mana stones can be used to empower magical artifacts in the hands of non-mages.
Mana Potions[edit | edit source]
Mana potions infuse a biological body with additional Mana. Spellcasters drink Mana potions to refresh their supply of magical energy.
It is considered unwise to drink a mana potion unless the imbiber has lowered their mana through magical activities. While the additional mana has the effect of energizing the person drinking that potion for a short time, this energy cannot be metabolized through other means than magical activity. The resulting effect is that of Mana Poisoning: Violent illness, fever, and uncontrollable bodily excretion. Too many or too potent Mana Potions can probably prove fatal.[4]
However, repeatedly drinking enough Mana Potions to risk Mana Poisoning can increase the imbiber's magical capacities. This is a practice that Ogres have mastered, and that Xrn has begun experimenting on the Antinium to foster spellcasters in their species.
Mana Potions don't mix well with alcohol. Drinking a mana potion when inebriated, triggers vomiting.[5]
Mana Exposure[edit | edit source]
If one is exposed to a great amount of magical radiation, it can result in a condition much more serious than Mana Posioning called Mana Overexposure. Also called meltblood overload and Internalized Apotheotic Magical Dissonance (IAMD), the hostile magic is infused into the afflicted's body and poisons them, leeching color from their hair and causing their body to gradually fall apart. If the victim isn't high level enough, it could melt their bones. To treat it, the magic must not be dispelled, as that would let all the magic out at once like an explosion. Instead, the magic in the patient must be concentrated to then be pulled out with mana-absorbing means, like sponges or magicores if necessary.[6]
