Notes

Defense Down effect is -25% defense.
- Additional Effect is -based, so it is unlikely to land on or enemies.
- Duration has three resist states, so "unresisted duration" is shown above, "resisted duration" is half of that, and it is possible for the monster to fully resist.
  - Duration scales continuously with TP, i.e. 1500 TP unresisted duration is 270 seconds.
