They took turns. Arthur cast a golem of his own and made it move towards the door in the front. After it got killed, the man from the Doom Order would do the same, and so on.
One thing they did was to mark the tiles that were safe, and the ones that they found traps in it.
"We still don't know if the tiles are static or change. So, after we find a safe path towards the door, we shall first send another golem to test the waters." Arthur said.
He was being careful after hearing George say those things about the power of the person who built that place. It was not someone that could be looked down on.
Arthur tracked the right path for them so that no one would perish in the first part of the strange place they were in.
After some time, the others picked up the spell as well, although it was not as good as the one Arthur and the original owner could cast.
Still, the golem was not meant for combat, but to trigger the traps. Even if it was a weaker version, it was more than enough.
