I'm sure Contrary is not affected by stat changes from Paralysis or Burn.
Contrary is only put into affect from stage drops, and stage buffs.
Meaning, that only moves like Screech, Metal Sound, Agility, or Sweet Scent will affect
Contrary and make them do their opposite intentions.
Stat drops from Paralysis and Burn should not affect Contrary, because they are calculated automatically
And by the way, Paralysis lowers your Speed by 25%. ~
