Evolve now or wait
from the game's learnsets and the relearner ruleGloom evolves whenever you use the Leaf Stone; the comparison below assumes you do it at level 28, the level you first meet it. Evolving then forfeits 1 move that Gloom would still learn: Moonlight at 35.
| Move you would forfeit | Level | Can you get it back? |
|---|---|---|
| Moonlight | 35 | No. The Move Relearner only teaches moves from the current form's own level-up list, so once it is Vileplume this move is gone. |
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.
