Aptitude[]

There is a sliding scale of aptitudes in Arcanum, defined as:

  • Neutral Aptitude: 0 means that the character is neither a mage or technologist.
    • This can be due to having no training or background in either field, or
    • Having both but being in perfect balance with each other.
  • Magical Aptitude (MA): 5 to 100 (or more) means that the character is magickally inclined.
    • They get progressively greater value from magickal items or spells.
    • There is also a progressively greater chance of equipped technological items causing a critical failure.
    • This works defensively as well by providing resistance from technologically based attacks.
    • Elves (+15) and Half-elves (+5) are born with natural MA.
  • Technical Aptitude (TA): 5 to 100 (or more) means that the character is technologically inclined.
    • They get progressively greater value from technological items.
    • They also get progressively less value from magickal effects on objects -- both bonuses on normal items and penalties on hexed items.
    • It also provides resistance to magickal spells, both harmful and beneficial.
    • Dwarves (+15) are born with natural TA.

Adjusting Technical and Magickal Aptitude[]

  • Putting character points into magic spells raises your magical aptitude/lowers your technological aptitude by 5 per spell.
  • Putting character points into technological disciplines and the four technological skills does roughly the opposite, but scales slightly higher.
  • Some character backgrounds, some locations, and some items can affect MA/TA.
    • Some backgrounds include Day Mage, Night Mage, Magick Allergy, and Elven Blood.
    • Some locations can include steam rail and train stations, tech and magick shops, factories, The Ring of Brodgar, etc.
    • Some combinations of background and location include Nature Mage and Sky Mage.
    • The Dark Helm can increase MA up to +20 (at the trade of alignment at equal and opposite measure) if ever equipped. This effect is permanent, and it is cumulative if the helm is taken off and then back on.
