So how do you obtain these rings? It’s simple. Cassandra gives you a challenge. Well.. Actually two challenges.
If you level up 30 times from your current level, you can get the Adventurer’s Cruel Ring. ()
If you level up from Lv. 1 ~ 50, you can get the Adventurer’s Cruel Ring (), Adventurer’s Critical Ring (), or the Adventurer’s Magical Ring. ()
You can get all three rings on one character. All you need to do is raise many characters to Lv. 50.
The Magical ring is excellent for my Evan.
