In OR and AS im trying to catch groudon with Adamant nature and perfect iv's (31/31/31/?/31/31) its taking forever so for now im battling on X and Y. Any tips on catching groundon with those stats. I got ralts with synchronize to pass on the nature. Then i have Durant with truant to use entrainment so i have more turns to catch him.
Well, all legendaries in ORAS come with 3 perfect IVs. This means the chance of catching one with 5 perfect IVs and a random special attack IV is:
(5C3/6C3)*((1/32)^2)*(3C2/4C2)
Normally the chance of getting the correct nature is 1/25, but having a synchroniser in the front of your party brings this up to 1/2
Hence the probability of any groundon you encounter being the right nature and IV spread is;
1/2*(5C3/6C3)*((1/32)^2)*(3C2/4C2)
or
o.5*(10/20)*(0.0009765625)*(3/6)
= 0.00122 or a 1 in 8192 chance
This means that to have a 95% chance of encountering at least one Groundon with those specifications, you'd have to encounter aproximately 24,500 Groundon.
Good luck.
Basically, use a masterball, hack or give up. Otherwise it's gonna take you forever.
