Still the best AoE unit in Slime! SMilim DESTROYS Glenda’s Beatdown Battle! (Slime: Isekai Memories) 

Charm used is blue souls protection gauge. Can probably get away with dark Atk.
This is what you get when you want to get the 2 dark characters mission done and the rest of the meta isn’t out yet. Not much to say about this fight, it’s pretty straightforward. Only the shield is an inconvenience, but gave me more time to stack.
