I agree wif mikezuper that it’s not based on the timing.
Also, what Pokémon you get from task is already determined at the point of collection of the task and not at the point of claiming the task.
I managed to get the shiny for Ho oh and also aero from task.
Can’t find the kabuto and omanyte and I think gonna be tough for me to find cos the spawn rates for these are very Low for me so getting a shiny will be very Low chance Liao.
My colleague was with me when she caught shiny kabuto . She clicked on the kabuto before i picked it up. I think if I have clicked on the kabuto before her, the shiny would have been mine.
I think shiny is based on a function of the trainer ID and the mon ID, both of which are unique. This would explain why shiny are individualized.
On same note, I do hope they implement some kind of "pity shiny timer" that greatly increases your shiny chance after a set period of drought time.
They have this in Diablo 3 for legendary item drops, and I think its a good measure
I have encountered one instance when it's shiny for both of my account and more often then not it shiny for one but not the other. What gives?
