Community-reported rarity
A player in the launch-window community specifically asked whether Arm was rare after seeing it on only one brainrot - consistent with our own documentation, where Arm is currently confirmed on just a single brainrot's kit (Dragono Demonico). Treat Arm as one of the least commonly seen moves until more brainrot kits are documented.
