A common problem in the event world is touched events. While we are unable to legitimately reduce the experience or level of a Pokémon, Effort Values (EV) can be reduced. To reduce Effort Values, you just have to give the Pokémon a specific berry. The table below shows which berry reduces which Effort Value.
| Effort Value | Berry |
|---|---|
| HP | #21 Pomeg Berry |
| ATTACK | #22 Kelpsy Berry |
| DEFENSE | #23 Qualot Berry |
| SP. ATTACK | #24 Hondew Berry |
| SP. DEFENSE | #25 Grepa Berry |
| SPEED | #26 Tamato Berry |
