Severin will be keeping an eye open for ambushes, so feel free to roll Perception checks whenever's appropriate.

I do have an idea for how to make the coming encounter slightly more favourable for the soldiers, and it could be argued that it's something that Severin might come up with on his own as a precaution, but really I only though of it after reading your IC post about the mutants sending out archers. Would you be okay with me suggesting it in IC anyway?
