What Smooth Rock does in PokeBonk
+1 bounce to basic projectiles (Projectile and Burst) and +10% projectile speed. Each extra copy adds the same bonus again, up to 3. Since version 0.5.3 bonuses of the same kind add together instead of multiplying, so 3 copies give +3 bounces and +30% projectile speed.
Items work on every move you carry, whatever its shape, unless the effect names a shape or a type. The pause screen shows each move's damage per second, so you can check what Smooth Rock adds mid-run.
How to get Smooth Rock
Chests are Poke Balls you buy with PokeDollars during a run; each one costs more than the last. A paid Poke Ball lets you pick one of three items, Great Balls from challenge altars and guardians are free, and Meowth's shop sells four offers at a time. Uncommon items show up from the start of a run.
Smooth Rock is one of the 35 items you must unlock: get 2,000 kos. Then buy it in the Lab for 250 Stardust. The PokeBonk Stardust guide lists the cheapest unlocks first.
