that is where you find it lol

most items like that are from wild pokemmon keep at it i spnt over 200k on pokeballs before the wipe to get my first dragon scale some get lucky on first one its random keep at it

but to be honest thats not what ya need to worry about lol its the being able to get a spot in game now with the limit at 50 its not easy to get a spot

a pkmn with frisk helps

pkmnlover is right. Using a Pokémon with the frisk ability may be more useful than spending a lot pokeballs. Frisk is coded in; it allows the Pokémon to identify the opponent's held item upon entering battle if the foe is holding an item. Horseas, in almost every map, if not all, has a chance to hold the dragon scale.
