I remember looking this up a while ago and I can't remember finding the usually chart so I'll ask here :3c Wondering because I finally got my ability changed on my Shiny Linoone, and am hoping to snag xp candies
Note: These items are only available at certain levels (e.g. Potion can only be found at 1-10), and they have certain odds to be found (e.g. the potion is common to be found at Level 1-10). Visit my source for a full list of those odds and levels.
They can pickup a veraity of items and better items at higher levels. if you want to learn more here: https://bulbapedia.bulbagarden.net/wiki/Pickup_(Ability)
