|The user crushes its target by rolling over the target with its rolled-up body. This may also make the target flinch.|
Steamroller inflicts damage and has a 30% chance of causing the target to flinch. Steamroller cannot make a target with a substitute flinch.
If the target has used Minimize, Steamroller now bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly.
