- Tornado pulses roughly every 3 seconds, starting at 3 seconds after transforming, for a total of 4 pulses. Each pulse inflicts damage and knockback.
- The skills granted while as Tornado set an effect that triggers a short moment after each regular pulse. The effect will be displayed in addition to the transform effect, corresponding to the name of the skill. The modifier will stay active until a new active effect is set or the transform ends.
- The granted stability is lost when leaving the transform.
- Elixir X has a chance to grant this transform.
