|Held item (5% chance) found on the following Pokémon:
The only way to get Dragon Scales is by taking them as held items from specific Pokémon that you can find via fishing.
Of the four species of wild Pokémon that can be found carrying Dragon Scales, Horsea and Seadra are the easiest to find.
Bear in mind that all of the Pokémon you can farm for Dragon Scales will be unavailable until after you’ve defeated the Pokémon League and received the National Pokédex.
Acquiring Dragon Scales
Both have the same high encounter rate of 45%, although Horsea might be a little easier to handle.
Route 226 lies to the east of the Battle Frontier.
Simply head eastward from the Fight Area until you reach any body of water, then start fishing with either the Good Rod or Super Rod.
Wild Horsea and Seadra have only a 5% chance of holding a Dragon Scale upon each encounter. So it might take a while before you get your hands on one.
However, you can greatly speed up the process by building a designated item farming team.
These special teams use Pokémon with the Abilities Frisk and Compoundeyes to both increase the odds of finding items, and to identify any item the wild Pokémon might be holding in each encounter.
If you’re using an item-farming team, the Compoundeyes Ability will raise the odds of a Horsea or Seadra holding a Dragon Scale from 5% up to 20%.
Frisk will also alert you to any items the foe is holding, saving you from wasting time on guesswork.
After discovering a Horsea or Seadra with a Dragon Scale, you can use a stealing move (like Thief or Trick) or catch the Pokémon to obtain the item.
Then you can end the battle however you prefer—you will hold on to the Dragon Scale even if you flee.
Dragon Scales: Details and Uses
The Dragon Scale is a held item with one purpose:
To make Seadra evolve into Kingdra via Pokémon trade.
After trading Seadra to another player while it’s holding the Dragon Scale, it will evolve into Kingdra.
Then you can trade back – although this evolution will consume the Dragon Scale.
Is Kingdra Worth Using?
Kingdra doesn’t excel in particular stat—rather, its greatest asset is its well-roundedness.
It has high base Attack, Defense, Special Attack, and Special Defense of 95 each, as well as a decent Speed stat of 85.
Kingdra’s weakest point is its HP, so it won’t absorb a lot of damage unless specifically trained to do so.
But it would generally be better to focus on improving Kingdra’s Speed and offensive stats than its hit points.
Kingdra will have one of two Abilities: Swift Swim or Sniper.
Swift Swim is the more interesting one—it doubles Kingdra’s swiftness while in the rain, giving it a maniacal base Speed stat of 170.
The drawback is that having Kingdra summon a rainstorm via Rain Dance leaves it open to foes taking advantage of its lackluster HP, so using this strategy can be tricky.
Good moves for Kingdra include:
