PLAY FREE Rock Stone in PokeIdle: Drops, NPC Value, and No Fixed Shop
Where to buy has a dull answer: the player market, plus the Pokémon that drop it.
Buy is the wrong verb on the official pages
The search is onde comprar, where to buy. I cannot point at a clerk. I can point at Cranidos and Tyranitar in the July 2026 catalog, and at the player market on World and io. Net does not use the stone to evolve, so buying one there does not move Larvitar or Cranidos.
On World the stone-versus-free choice still matters. A stone keeps your level. The free path resets you to level 1. Paying a player for a Rock Stone is paying to keep the levels you already farmed. That tradeoff is the useful part of this page, and it is spelled out again on the evolution guide.
Species pages: Cranidos and Tyranitar. Do not confuse this item with Bronze Boss Token, which is a trophy rather than an evolution reagent.
Before buying a Rock Stone, separate the intended evolution from the item’s name. The World evolution recipe and the io market are different systems, so a guide for one cannot identify the other game’s seller.
