We have:
Detect Enemy (spell) (Amp Level 2): When Surprise Threat is played, the mage gains a Plot Point. (This represents the mage's ability to see trouble coming and Double time it or Shake it up, etc. and it only works when enemies show up, not other threats like tripwires or traps.)
Phantasm (spell) (Amp Level 1): Creates convincing illusions of objects, people, or scenes. (This is just a story telling trick and does not affect dice.)
