What Thunder Stone does in PokeBonk
Your critical hits fire a bolt at a nearby enemy. Each extra copy adds the same bonus again, up to 5. Since version 0.5.3 bonuses of the same kind add together instead of multiplying, so 5 copies give +0.2 crit chance.
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 Thunder Stone adds mid-run.
How to get Thunder Stone
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. Epic items are rare early in a run: their odds rise with your player level, your luck and the zone you are in, so luck and later zones help.
Thunder Stone is one of the 35 items you must unlock: paralyze 600 pokemon. Then buy it in the Lab for 1,000 Stardust. The PokeBonk Stardust guide lists the cheapest unlocks first.
