Lake Acuity as shown in Pokémon Legends: Arceus
Lake Acuity is one of the three lakes in the Hisui region, being located in the Alabaster Icelands. It appears only in Pokémon Legends: Arceus.
When the player is tasked to make the Red Chain to “bind the world together”, they will have to go to Lake Acuity where they face an alpha Zoroark at level 58. If the player is successful in defeating/catching it, Uxie will then appear, beginning the player’s trial. It tells them a riddle via telepathy, which asks the player to guess how many eyes Combee, Zubat, Unown, Magneton, and Dusclops have; which all have to be thrown in a single answer. Answering correctly will award the player with Uxie’s Claw, one of the items needed to create the Red Chain.
