I managed to score Calliope’s Legendary weapon, named Boris, a while ago and had to grind up to L10 to use it.
Got there a day or two ago and it is seriously scary. The red die ability is double damage Injure for 2 turns. Non-bosses rarely last longer than one.
And scoring a critical hit gives you this cool/creepy thing I finally managed to framegrab. Hi, Boris…
I always thought Calliope could hit way above her weight class, grabbing Boris makes her even more nasty.
