Cinda, the fey Sorcerer who is not found of all of you.
Greg, the foot bard.
I don't care how uncomfortable Cinda and Greg are when I approach them. Once there, I ask if they're capable of casting Dimensional Anchor and if they'd be willing to come with us next time we head out into the battlefield.
I know she has a fractured ego since we broke her enchantments (and spirit) last time we encountered her, so if it helps, I allow the Cinda the honor of touching my muscles while I plead our case. I flex with every syllable in order to convince her. I speak loudly and obnoxiously to cement my power and charm. I put every ounce of my 3 Charisma into convincing these two to join the fight.
