Arcane

Arcane Spells involve the direct manipulation of mystic energies. Bards, Sorcerers, and Wizards cast arcane spells.
Bards and sorcerers use Charisma to cast, while wizards use Intelligence.
As opposed to Divine spells, Arcane Spell Failure from armor is a factor for most arcane spells (see: the Somatic Component for why).
