Description
A Key Stone is a Pokémon item that, when used on a Pokémon holding its respective Mega Stone, causes a Pokémon to undergo Mega Evolution. Key Stones are commonly embedded in an accessory or personal item kept by a Pokémon trainer, such as a Mega Ring.
They can be differentiated from Mega Stones by their yellow-green to purple gradient coloration and the Mega Evolution symbol with slanted diagonal lines within.
For the sake of searchability Key Stone should NOT be tagged as a Mega Stone, unless there's one present in the same image.
For example:
thumb #6003156 ▷ Shouldn't be tagged as `Key Stone (Pokemon)`
thumb #1472059 ▷ Should ONLY be tagged as `Key Stone (Pokemon)`
thumb #5332298 ▷ Should be tagged as `Key Stone (Pokemon)`, `Mega Stone` AND `Glalitite`
