Electrizers are items introduced in later Pokemon games that allow you to evolve certain Pokemon into their electric type evolutions. They are not available in Explorers of Sky.
To evolve Pokemon in Explorers of Sky, you need to meet specific conditions, such as:
* Reaching a certain level: Some Pokemon evolve simply by leveling up.
* Learning a specific move: Other Pokemon might evolve after learning a certain move.
* Trading: Some Pokemon can only evolve by being traded with another player.
* Specific locations: Certain Pokemon might evolve in specific locations, like the Valley of the Wind.
If you are trying to evolve a specific Pokemon, check the in-game Pokedex or online guides for the evolution requirements.
