Rage deals damage, and if the user is hit by a direct attack - any time after Rage is first used but before a different move is used - the user's Attack is raised by one stage. The game will state the Pokémon's rage is building rather than explicitly assert the stat increase. Stats can be raised to a maximum of +6 stages each.

The Attack increases will continue as long as Rage is the last move used, even if it misses, the user is incapacitated (paralyzed, sleeping, etc) or the player uses an item. The Attack increase activates for every blow of multi-hit moves such as DoubleSlap or Fury Swipes.

As an example, if a Pokémon uses Rage then the opponent hits the user in the same turn, the user's Attack increases. If the user moves last it will not increase that turn, but will in the next turn if the opponent hits the user again.

When a Pokémon is holding Normalium Z and uses its Z-Power, Rage turns into Breakneck Blitz and has base power 100.
