Clearly, I've made a mistake. Apparently, dropping the burning item wasn't enough, as the burn has spread to my upper body. I throw myself in the nearest murky pool, hoping for the best.
Meanwhile, the humans continue to die.
I managed not to burn myself. After the smoke clears, here's what's left of floor one.
And here's floor two. Among the dead was the town's Axe Lord. No one minds if I just take his stuff do I? No? How nice of you.
All in all, having only done this twice now, I could've planned that much better. If I'd been a little more patient this time with waiting for folks to catch on fire, my Adventurer here would've have gotten his burns.
Also, if I seeded the upper floor of the mead hall with corpse-kindling or even just leather items on each tile that'd also gone easier. The fire won't naturally spread there from the first floor, but it also requires exactly one thrown burning item to land on the second floor to spread the love around. And again, it's problematic because carrying enough items for every single available tile would put quite a weight on the adventurer. But there's less floor space upstairs and a greater concentration of folk. A chain of corspses to just inside the door, ending at an easily thrown item and as many corpses as possible to place kindling on the second floor might work out best.
