Oh My...
Every Immortal Ring had a special cadence to it. Much like how Mental Realm Masters could use Chanting to increase the strength of their Visualizations, certain Immortal Rings could be summoned with greater speed in battle by reciting a mantra that suited them. This was why during his battle with Izril in the dream world Osiris, Ryu had heard him say 'Blossom Forth'.
However, the trouble was that Ryu's mantra was far too overbearing. Even though common sense told Arteur that this was all that it could be, he had an unwillingness to accept it. In fact, he was unwilling to accept it for more reasons than just this.
Once one stepped into the Dao Pedestal Realm, Immortal Rings could no longer be summoned. Only very special techniques allowed for the continued use of Immortal Rings, but in most cases, the Immortal Rings would fuse with the body once one cleared the Path Extinction Realm.
