Weirdly, that was easy. I split up my team, targeted the wine barrels, iced up some of the camp floor, dropped Spike Growth, and just went to town. The hard part was that one guy inside on the throne. He had two attacks and action surge, and would one-shot whomever je targeted. The goblins were cake.

Managing spell slots is tricky, though. Have to decide carefully whether using any is warranted for a given fight.
