Thank you all so much.
I already passed it by changing a lighter sword.
and I have question on"prime pathing" now.
here is the link:

My hero can't move in prime pathing

def Primes(trap): for div in range (2,Math.ceil(Math.sqrt(trap.value))): if trap.value % div == 0: return False self.say(trap.value) return True traps = self.findByType(“fire-trap”) P = [] for trap in traps: if Primes(trap): P.append(trap) nearest = self.findNearest§ if nearest: hero.move(nearest.pos) friends = hero.findFriends() for friend in friends: hero.command(friend, ‘move’, nearest.pos)
