Hello, seeking some advice from the community. Last night my party had an epic encounter with Bavlorna with her fleeing a battlefield full of evil stunning strike and silence spells.

My players decided they wanted to do a rush job in looting the cottage (duo true-sight & detect magic), and then burn it down, with the aim of getting as far away from Downfall before Bavlorna's possible return.

According to the manual: Walls and Windows. The cottage’s walls are made of soft, mossy wood and don’t burn easily due to the moisture trapped in them.

So, do I just make them do extreme amounts of fire damage to burn down the cottage, or should the cottage just physically walk away from receiving crippling fire damage...
