Storming Terror VI has been completed and Level 90 Dvalin has been defeated with only Jean and without taking damage or having no food buffs whatsoever. Character build is shown at the end of the boss fight.
During the time that I was gone, I've gotten Jean up to C6 finally to honor and celebrate her birthday. The only thing now to complete her is an R5 Primordial Jade Cutter, which will evidently get a rerun at the same date Natlan will come out.
