Hello, Im trying to get my hands on Dragon Scale for Horsea and Metal Cot from Magnemite by using Thief on them as it is faster than catching but for no avail... Is it posible to even get those items from them by using thief or am I simply unlucky?

You are able to get them. The pokemon has a 5% chance of holding an item.

Make sure to have an empty item-slot on the pokemon you are using thief on as the item will go to your item-slot after you stole one.

Oh okey so the chance is just low but it's still possible. Thanks for a fast reply.

Locked as resolved.
