Dude, such luck!!
I was trying to get a Shiny Haunter because I saw how awesome Shiny Mega Gengar looked, and I found a shiny patch at a chain of only 6!!!
The haunter is docile with mediocre IVs (evenly spread out, all of them around 15-17). I tried to continue the chain but it randomly broke at 37, but whatever, I'm gonna use this Shiny Haunter X3
