- Marcette requires a freshly extracted stroper stomach for her latest experiment. Use the medicine she has provided you to neutralize its foul breath, then slay the creature and extract its innards.
- You have obtained the putrid stomach of a stroper. Deliver the foul mess to Marcette before you pass out from the unbearable stench.
- Never have you seen anyone so happy to receive a putrid pile of innards. Marcette is once again tremendously pleased with herself, and-- from the fact that she remembered your number-- might even genuinely appreciate your efforts this time.
