The Trial of Lake Verity

Description: In order to obtain the Red Chain, you must clear the trial set by the Pokémon that protects Lake Verity in the Obsidian Fieldlands.

When you go to Lake Verity, your Arc Phone will react and open up a hole in the cave. Inside you will find an Alpha Goodra which will challenge you. Defeat it and Mesprit will appear and ask for how you felt when you were expelled from the village. Answer correctly and it will leave and give you Mesprit's Plume
