Koffing shiny in PokeMMO

In PokeMMO, each wild Pokémon has a 1 in 30,000 chance of being shiny. Donator status and the Shiny Charm each improve it by 10% (about 1 in 27,000 with one of them).

Hordes are the fastest way: with Sweet Scent, every Pokémon of the horde rolls its own chance, so a horde of 5 gives 5 chances per encounter.
