Suggest a spanking.

"A spanking!" you call out. "Tie her down and give her a spanking!" Your voice cuts through the crowd. Gudrun nods in agreement.

"By Ruthi's shield!" she says. "A good honest spanking it is!" Livia's face turns very red as the barbarian woman drags her towards a convenient table. Soon enough she's bound face-down over the table, ankles and wrists tied to the legs and a cushion slipped under her pert little bottom to raise it into the air. A perfect target. The crowd gathers round to watch the fun. Gudrun places a hand in the small of Livia's back, pinning her down and preventing her from wiggling around.

"Take it like a warrior," she orders, caressing Livia's heart-shaped buttocks as the necromancer girl squirms and shrieks obscenities. "A naughty little bare-bottomed warrior. Ready?"

"No!"

The sound of the first smack rings through the tavern. Gudrun is a strong girl, and she hits hard.

"Owwwww!"

Everyone laughs, including you. Livia is getting seriously angry now, but she can't do anything about it. Fury and frustration brim in her eyes, but there's no escaping her humiliating predicament. She's stark naked with her ass in the air, getting firmly spanked by a total stranger while a bunch of other strangers laugh and tease and mock. All she can do is brace for the next impact.

The second smack is even louder than the first one. "Owwwwwwwwww!"

Several minutes later, Livia's bottom is glowing just as red as her face and Gudrun is stepping back to give somebody else a turn. She beckons you forward. "This was your idea, wasn't it? You deserve a go at her."
