At the Tower of Mastery, Gurkinn offers a single Mega Ring to the player and their friends, but due to only having a single Mega Ring to give away, requests that they decide among themselves who should receive it. Of the group, only the player and Serena/Calem are interested in receiving it, so the two battle to decide who should receive it. Upon defeating Serena/Calem, the player must obtain the Rumble Badge at the Shalour Gym and then go to the top of the Tower of Mastery to receive the ring from Korrina.
After the player has entered the Hall of Fame and visits Kiloude City, Calem/Serena will battle the player once per day here, having obtained their own Mega Ring.
After the player has defeated their rival in Kiloude City once, at the Anistar SundialProfessor Sycamore will upgrade the player's Mega Ring by having the player touch the sundial. Once upgraded, the player can then find hidden Mega Stones around Kalos from 8:00 PM to 9:00 PM.

In Pinsir Glares, Y was made a Mega Evolution successor by Gurkinn and given a Mega Ring outfitted with the Key Stone from Gurkinn's Mega Glove. With it, she can Mega Evolve her Solsol into Mega Absol.
