Vahagn "only" has a A frame debuff that Fire otherwise has NO access to to (-10% from a R doesn't count, okay?) and at the same time deals 1.65x damage compared to your other Hime (applies 5/8t, and only if at full health). This alone makes Vahagn a complete beast in some content, but she also has 5/8t guaranteed Triple.
Vahagn requires high health to be properly good so isn't ideal for all content, but her debuff is always welcome. Except in debuff immune content. But debuff immune content is stupid.Standard: Tier 1
Elite: Tier 2
Legendary: Tier 3
Upcoming to Nutaku later with absolutely insane costs that you will never farm as a new player so get fucked: Tier 4
