Ysolde the Scribe
Epic Mage also in the gacha
She copies inscriptions no one can read and swears they repeat: always three letters, a dash and three numbers. She calls it a proper name, and she shivers when she says so.
How to get
Defeat the boss of the Ice Caverns. Ysolde needs twenty quiet minutes at the far wall.
Unlocks at: Ice Caverns
The gacha hands this companion over sooner — the free path still stands, and it is the same for everyone.
