I looked at your seed and realized the frame numbers you're citing are Method 1 frames. Regigigas and other stationary legendaries use Method J. (If you search Method J for your seed, you'll find you'll need a Jolly synchronizer at the front of your party and aim for Method J frames 469 or 471. [This means you might want to remove your wanderer...])
.... T_T
Dang, and I've got like an adamant one with me in my second slot...
Well, I'll just finish out the journal flips and steps and see if it magically works and when it doesn't I'll come back with a Jolly.
I do appreciate your help.
Noob question alert!
Why does it matter method J or 1? The spread I got twice showed up when i searched for it under method 1.
Oh, and what does removing the wanderer do besides take away that one RNG advancement?
[edit] yeah got a gentle one. Start over. at least I know I've got the general process down! :D
