>>44851454You have to decide with the rules yourself. I avoided dens in my run because I thought they were too strong for a nuzlocke, but they have enough risk that you could do it. But obviously once you check you have to commit.
>Can we pick the pokemon from the overworldPicking ruins the point of a nuzlocke. You can either close your eyes and walk around randomly into a zone to catch overworld mons or do random grass encounters.
>What if it's too strong to catch initiallyThen it doesn't count, obviously. Same reason the pokemon you find on a route before you get pokeballs don't count.
Protip that isn't documented on any of the wikis: catch rate absolutely plummets when your current pokemon is below the level of your target, which will happen a lot in a sw/sh nuzlocke where you're probably limiting your level.
