Shiny Slugma is Slugma's shiny form: a different colour, and stronger, with 30% more health and move damage than a normal Slugma. Shinies are the strongest Pokémon in the game.
How rare it is
Every Slugma you defeat on a map has a 1 in 2,500 chance to drop Shiny Slugma. A hunting chain on Slugma makes it up to 4× likelier, and the Shiny Charm 1.5×.
Where to find it
Beat Slugma on these maps (a shiny sometimes defends a map itself, stronger than its kind):
| Map | Region | Level |
|---|---|---|
| Fiery Path | Hoenn | 60 |
| Lavaridge Gym (Flannery) | Hoenn | 58 |
Evolving it
A shiny evolves into the next form's shiny, which is rarer, so it also needs Glimmer Stones:
- Evolves into Shiny Magcargo with 3 Glimmer Stones, on top of what Slugma needs
Past level 100
A shiny never becomes a Nightmare form: at 5★ and level 100 it Ascends instead, keeping its shine and its name, and climbs the Nightmare ranks to level 999. See The Nightmare World.
