So I am soft resetting for shiny lugia, and I decided I would attempt to catch it just to make sure I will be able to catch the shiny. First try went smoothly, and I caught it. Second try however, it killed my Pokémon that put it to sleep AND my false swiper, and eventually commited struggle suicide. If I go buy some healing items and train my false swiper a little, and come back and save and start soft resetting again, would that be ok? Or would that somehow have a negative affect on something. Please help!
There would be absolutely no consequence to pausing the soft resetting to do something else. Soft resetting doesn't increase your chances like a chain, so nothing bad will happen.
