Special Rules:
Any investigator may sacrifice two sanity for two clue tokens as man times as they want per turn. ...
Would this ability be the same as Duke's or Flesh Ward's?
For example you fail a Horror Check vs. a Dhole and instead of losing the 4 sanity you pay 2 sanity for 2 clue tokens and spend a clue token to try and pass the Horror Check or would you have to anticipate the failure of the Horror check so pay the sanity before the Horror Check?
