I'm doing Act 11 arrow 1, which is Jason support vs Caenis. She has a buff that basically makes her invincible. The battle should have lasted 3 turns yes? Well with Saber Alter's rank up quest which gives her an ignore invincible buff.
The battle ended in one turn haha, her invincibility is gone because she got damaged. Just sharing because it's funny.
And with "What...!?" makes it even funnier.
