Shell Side Arm forecasts whether its base damage would be higher as a
physical move or
special move, and becomes the category that it predicts would inflict more damage (chosen randomly if they are tied). For the forecast only, stat modifiers other than stat stages are ignored, and
Wonder Room is applied to stat stage modifiers but not to the original stats.
Shell Side Arm has a different animation depending on whether it is a physical or a special move. If it is a physical move, it makes
contact; if it is a special move, it does not.
