If the wielder attacks and the target's ability would prevent the effects of the attack from taking place, or hinder the effects of the move, the ability is temporarily nullified while the attack is in progress. Abilities that prevent status, such as Limber or Magma Armor, are also deactivated during the attack. This allows a Pokemon that has one to be affected by the status they prevent, but the ability will cure the status immediately after all effects of the attack resolve. Turboblaze also gives a message when the wielder switches in stating that it has Turboblze. Turboblaze does not nullify abilities for the duration of either Future Sight or Doom Desire that was used by another Pokemon.
Abilities nullified are:
Reshiram can make some use out of this ability, hitting Heatran, Snorlax, Heatproof Bronzong, and Mamoswine for full power, and breaking through Forretress's and Skarmory's Sturdy. Otherwise, it is a rarely useful ability that can only really make a difference once every so often.
