Upon starting the battle or switching to Speed form, generate a number from 4 to 6. Stay in Speed form for that many turns, and shift to dragon form at the end of the turn after the counter reaches 0.
Shift to dragon form after losing over 10% of max HP in one turn.

If HP is below 76%, 30% chance to cast (262) on any given turn. (Standard targeting.)
If HP is below 76% and any party members have an ailment, 30% chance to cast (259). (Targets party members with an ailment.)
If HP is below 50%, and a party member is asleep:

40% chance to cast (259) (Targets party members with an ailment.)

40% chance to cast (261) (Standard targeting.)
