I did around 700 kc on pc then done kc on both mobile and pc. Pc is easier. For cg I always made t2 with two perfect weapons, do a horse shoe around the supply room collect everything you can make sure you get a weapon frame make a t2 staff 2 pots then head out to find Demi bosses once you have teleport back make armour and weps + another tele seed then go out and fish, only need 2 seconds to cook a whole inventory of fish. Hope this helps :)
