The Trial of Lake Acuity

Description: In order to obtain the Red Chain, you must clear the trial set by the Pokémon that protects Lake Acuity in the Alabaster Icelands.

When you go to Lake Acuity, your Arc Phone will react and open up a hole in the cave. Inside you will find an Alpha Zoroark which will challenge you. Defeat it and Uxie will appear. It asks for you to answer a knowledge question. It asks for the amount of eyes on Combee, Zubat, Unown, Magneton and Dusclops and asks you to put it as a number; 60131. Answer correctly and you'll get Uxie's Claw
