ShadowMario3 | Pokémon Violet - Unrivaled Meganium 7-Star Crystal Raid Solo @ShadowMario3 | Uploaded April 2024 | Updated October 2024, 8 hours ago.
Unrivaled Meganium has arrived, and it seems to be a doozy. It opens up with Reflect and Light Screen before using Curse to take you down. I use a Skeledirge this time around thanks to its hidden ability, Unaware.

Skeledirge @ Shell Bell
Ghost Tera
Ability: Unaware
Modest, 252 Special Attack and Defense
- Torch Song
- Shadow Ball
- Protect

With Unaware, you will ignore Meganium's stat changes. So all you need to do is use Torch Song until you feel you have enough boosts (I did +4) then use a Tera Shadow Ball. When it resets your stats, you should Protect, then repeat the process until you take it down.
