Pretty sure, Sherry's right click dmg is closer to Claudia than Sybilla.
Their roles are also different.
Sherry is for group clear (post skill AW), similar to a mage-armor in play style, but with a bigger aoe. (not in nutaku yet, but think them like a melee mage) https://www.youtube.com/watch?v=te8FVTFjXnY
Claudia is for boss fights. Against later game bosses that have composite armor. (high mr + high armor)
It should be noted that skill awakenings are be quite tedious to obtain, unit must be
1. Awakened
2. Maxed skill 5/5 or 10/10 etc (pray to RNGesus)
3. Have nutaku patch in updates for class skill AW (princesses came around dec last year)
4. Pay same cost for awakening to skill awaken. 250k+2 orbs for plat
While claudia needs straight up SC. (there are somethings that money can buy, for everything else, masterbed)
Can anyone confirm if Claudia gets nerfed in a future patch?
