Frost Claw does nothing on the turn it is selected, other than state that the user has taken in cold air. On the following turn, Frost Claw will inflict damage, PP will be deducted from it, and it will count as the last move used. Once Frost Claw is selected, the user will not be able to switch out until it is disrupted or fully executed.
Frost Claw will not need a turn to charge if used under Hail. It will only deal half of its normal damage if used during Harsh Sunlight, Rain or Sandstorm.
A two-turn attack. The user gathers cold air around claws, then it slashes the opponent on the second turn.
