How far did the river carry him? Like a flashflooded river river could be 15mph. If he was unconscious for an hour, maybe he could walk back in a day or two.
Wait, isn't the support guy near the entrance? How come none of the heroes or robots saw him tied up on their way in or out of the place? Or maybe mc hid him behind a wall. Guess he died in the giant fireball.
I forgot if mc has item box. Doesn't he keep all his tools and totems in it? Couldn't he put the staff inside as well? Or cover it with a cloak or blanket, random townspeople wouldn't know if it was a spear or polearm.
Best answer to the trolley/carriage question is to run over the pedestrians, then send the passengers down the cliffs afterward. Kill all humans, leave no witnesses. 🤖
