Evolution
3 stages
Gastly
Haunter
GengarEvolves into Haunter at level 25.
Evolve now or wait
from the game's learnsets and the relearner ruleGastly evolves at level 25. Nothing is lost by evolving straight away: every move Gastly learns after that, Haunter learns too.
Rule the game applies: the Move Relearner on Two Island (he takes two Tiny Mushrooms or one Big Mushroom) teaches only the level-up moves of the form you hand him, at or below its current level. Delaying an evolution costs the evolved form's higher base stats for every level you wait; a move you barely use is not worth that.
