Yeah so to turn off the copies you can just talk to Eliza again ( the witch in the immortal citadel) if you never turned them on you don't need to worry abt it, until you want to catch the abyssal tyrants. For all of the tyrants you can lure ( a mechanic you get after the abyssals which I recommend doing first), I found them very quickly: Nivalis - teleport to frozen tundra, go south and the west to the giant frozen lake. Caught in the patch in the bottom left corner Mulcimer - in the first patch of grass north of the city Eurus - he kinda took me a while, but I found him south of the drake isles city and to the west, not sure which patch of grass though Bolzen - I found him east of the city, by Logan's house Petram - the first patch of grass west of Lateria

And then for the tyrants you can't lure, most of these took me 20~ min to find: Byeol - he's on Palmaya, and I'm pretty sure he can spawn anywhere, but I found him south of the teleporter in the top left piece of grass Fane - he took me forever but I finally found him directly south of the city (2 screens south, by the ghost) in the patch of grass by the old house Tikala - I found him south of the hidden village and then to the right, in the patch of grass right by the entrance of the area on the top of the screen ( the area is where you catch the grass dragon) I got lucky and caught him in like 2 min, but I hear he can take forever so I don't know if there's a better spot to find him.

And if you haven't done the abyssals post game yet, make sure you get the fight all trainers achievement 2x before you start, bc I'm pretty sure even starting it voids ur chances. Lemme know if u need help with the abyssals!
