March the full force (party + guards) to the moat's edge in full view. Make a show of overwhelming strength. Demand the bandits surrender - Kella is dead, there's no reason to keep fighting.
Tactics
- Display strength: Line up party and guards at the moat, weapons visible
- Kaltor in full armor at the front with guards
- Barzer and Nysera visible with spell components ready
- Deliver terms (Elaris as speaker - CHA +4):
- Kella is dead - whatever deal they had is over
- Surrender and leave peacefully
- Refusal means no quarter
- Set a deadline: Give them one hour to decide
- Be ready: If they refuse, execute the Moat Ambush
- During negotiation, party is already in ambush positions
Pros
- Might end without bloodshed
- Demonstrates strength and control
- Bandits may question why they're still fighting
- Prisoners mean information about what Kella was planning
- Moral high ground - you offered mercy
Cons
- Gives bandits time to prepare defenses or plan escape
- They might call your bluff
- Splits the party's attention between negotiation and combat readiness
- Unknown how loyal the bandits were to Kella
Best If
You want information, prefer diplomacy, or want to minimize casualties on both sides.
