Edit [engine/ ### `EvoStoneEffect`: Mist Stone -TODO +A Mist Stone is a rumored item from Gen 1 that evolves Pokémon into "PokéGods". A more realistic function would be to evolve Pokémon like Machoke or Haunter that otherwise require trading, which can be inconvenient. + +First, add the essential data. Replace `ITEM_64` with `MIST_STONE`; give it a name, description, and attributes (`item_attribute 2100, HELD_NONE, 0, CANT_SELECT, ITEM, ITEMMENU_PARTY, ITEMMENU_NOUSE`); give it the `PokeBallEffect`; and remove `ITEM_64` from `TimeCapsule_CatchRateItems`. + +That's actually all you need to do for the item itself. Now as long as it's declared to evolve a Pokémon, it will do so correctly. + +Edit [data/pokemon/evos_attacks.asm](../blob/master/data/pokemon/evos_attacks.asm): + +```diff + KadabraEvosAttacks: ++ db EVOLVE_ITEM, MIST_STONE, ALAKAZAM + db EVOLVE_TRADE, -1, ALAKAZAM + db 0 ; no more evolutions + ... + + MachokeEvosAttacks: ++ db EVOLVE_ITEM, MIST_STONE, MACHAMP + db EVOLVE_TRADE, -1, MACHAMP + db 0 ; no more evolutions + ... + + GravelerEvosAttacks: ++ db EVOLVE_ITEM, MIST_STONE, GOLEM + db EVOLVE_TRADE, -1, GOLEM + db 0 ; no more evolutions + ... + + HaunterEvosAttacks: ++ db EVOLVE_ITEM, MIST_STONE, GENGAR + db EVOLVE_TRADE, -1, GENGAR + db 0 ; no more evolutions + ... +``` + +(Note that if a Pokémon has too many evolution methods, they'll say "NOT ABLE" to evolve with an item even if they are.
