To see 5 shiny
See how many liao
Avg gotta catcy 700 to see 1 right
It's all RNG. I don't think there is really a caught how many to see how many formula. Usually during special event such as the Gen 3 event week (where all pokemons were gen 3) the chance to tio shiny might be better.
For main account, pokedex showing Swablu 615 SEEN and 574 CAUGHT. Result 5 Shiny.
I think 2 were caught during the Gen 3 event where Swablu was everywhere.
3 others were caught after the Gen 3 event.
First 4 were caught a while ago probably before 500 CAUGHT.
I remember it's been a while since I came across Shiny Swablu. Today was the fifth one.
My secondary account SEEN 537 CAUGHT 509, caught all the same Swablu, 0 Shiny.
But my secondary account also quite steady on his own, caught Shiny Sableeye (within the first 10 caught), Poochyena and Aron when there were no special event. Cannot complain liao.
