@stilgar: Yeah, the unique sets are OP (yes, I said sets, plural, guess who else's getting them), although the condition (admittedly easily cheesed in 'real' MMO by just making a new account/character) of solo clearing the boss on first attempt is certainly very hard.
@depzdai: It's her mix of skills that made it happen. Her massive Vit (with 4x multiplier from the rare ring + the skill she got by tanking a rabbit for lulz...btw iirc in the novel the condition is to fight an enemy appropriate for your level, do no damage, AND take no damage, for a long period of time) prevented the hydra's attacks from doing any damage. Then her poison resist made the poison breath manageable without healer at first, then as she tanked the breath for god know how long with her Meditation, she eventually became outright immune to it. After that it's the power of nom nom.
And now begin the adventure of the most innocent invulnerable poison spitting little girl.
I didn't read too far into it back then, but for anyone who think she's OP.
Yes she is, even by the game standard of having unique set.
So the Dev have to nerf her, directly and indirectly, after she basically faceroll people in a battle royale event (tank everything, poison any fool who get close)
Directly - her skills get nerfed (forgot the specific)
Indirectly - classes get some type of defense piercing attacks, so stacking def to laugh it off is no longer possible (especially with her 0 agi's waddle pace)
