In the run where I got both of these I turned Seras into a poison shotgun with a giants shortsword+Circlet of Acuity. Voss died to 666 poison dmg and it was hilarious, and he put enough stacks on Krog to get his mission too
Acessories! Also I have finally gotten all 16 skins, Seras was my favorite quest, Mamu's took doing a double mamu run to unlock though
Im glad some of the quests were fun too. The shield potion helps alot
OHMYGOD I COULD HAVE USED BUBBLE BREW THE WHOLE TIME
i accidentally unlock mamus, i quit a run just as it started and it gave me the costume.
