>>15083109Wow, you're an idiot.
Go to Lumiose City and go through some of the alleys and smaller streets. There are trainers there. You can pick them out from normal NPCs cause they don't move around really.
There is one in particular that says something about missing somebody special. When you defeat her meager single pokemon, she will give you a Destiny Knot.
This is repeatable anytime you enter a building and come back out. There is an infinite supply of Destiny Knots in Lumiose City.
I remember when that one anon called me an idiot when I pointed this out because "who would ever need more than one Destiny Knot?? HURR".
Too bad, OP. You fucked up.
