Some creatures have a connection to a specific tradition of magic, whether because of a mystical bond with a divine power, a connection to another plane, or simply because they've studied magic. Magical adjustments are especially appropriate when you want to incorporate a sci-fi creature into a game with heavy fantasy themes.
- Decide what tradition the creature's magic comes from (arcane, divine, occult, or primal) and whether the creature's spells are associated with its Intelligence, Wisdom, or Charisma. Increase that attribute modifier to reflect the creature's association with magic (typically you'll increase it by 1 or 2, up to the creature's other highest attribute modifier).
- Add innate spells from that tradition to fit the creature's theme and purpose. A good rule of thumb is to choose about three spells of up to half the creature's level that grant it something especially memorable or useful that it can do, but you can choose spells of any rank as long as they fit the creature's niche and power level; full guidelines for creatures' innate spells can be found in the Spells section of Building Creatures in GM Core.
- Add the following ability.
Magical Resilience [reaction] Trigger The creature attempts a saving throw against a spell or magical effect of its magical tradition but hasn't rolled yet; Effect The creature gains a +1 circumstance bonus to its saving throw against the triggering effect.
