Methods of hunting shinies in insurgence.
However, the shiny chance is 1/8192 everywhere in insurgence, be it the wild routes, friend safari pokemon or in-game trades from NPCs. Only exception is pokepon but it has a time+steps constraint.
You’d probably get the shiny charm somehow in 1.2 if you complete the dex.
There’ll be dexnav in 1.2, which would make shiny hunting easier.
Once you load the text for egglocke, you can’t load any more eggs into that save iirc. You’ll have to start a new challenge.
The egg generator that you mentioned is only useful for egglocke challenge mode. You can’t use it for any other playthrough. Your friend is probably pulling your leg.
