I cobbled this party together for Genesis damage shenanigans, when I decided to try a combo I never thought to use before: Thirty Seven + Aid Six. I only really wanted to see if Six's Incantations would let Thirty Seven cheat her Follow Up Attack faster (it actually does!)
Despite that, I was not expecting Thirty Seven to hit 1.7M damage using Six's Ultimate. I legitimately don't have an explanation for this, I was not paying much attention to this run (I actually realized halfway through that I forgot to change out certain artefacts)
