This demon was irritating.  First it eats her doll, then it tries to eat her and now it's spewing some corrosive substance everywhere!  Hah...  "How tiring." Katherine grumbled to herself as she once again recalled her dolls to her rings and making sure of each step she made to not step a single toe into any of the acid the made it's way toward her.  As the rat girl threw the ball at her, Katherine caught it.  And Myrilla said... Catnip?  "She's the one that snuck the catnip in my room!?"  Damn that woman.  

Still, if she remembered right, this demon was still not sealable yet.  "Fine."  She summoned her dolls out to safe places so they could open fire on the almost defenseless demon.  The ones with melee weapons she summoned closer toward said demon to try and cut the tentacles off after all, what use were they if they couldn't project corrosion near as far as she wanted. "Volley!"  The firbolg commanded right as her dolls pulled the triggers on their rifles.  She mouthed the words for the seal's chant, making sure she were ready for when she could do so.
