Arm Thrust inflicts damage, hitting the target 2-5 times per use. There is a 33.3% chance that it will hit 2 times, a 33.3% chance that it will hit 3 times, a 16.7% chance that it will hit 4 times, and a 16.7% chance that it will hit 5 times. Ignoring the possibility of missing, it will hit 3.168 times on average, giving it an average power of 47.52.
Pokémon with the ability Skill Link will always hit five times when using Arm Thrust unless it misses.
Arm Thrust may continue attacking after breaking a substitute. Bide and Counter will only acknowledge the last strike of this move.
If the target is holding a Rocky Helmet, the user is damaged for each strike. If the target has an ability that activates upon contact, each strike counts individually, enabling the ability to activate multiple times.
