Trials and tribulations
Lumen threw aside his fear of the environment doing everything it could possibly do to try and kill him. In place of this fear, courage came as he decided to go over to the now wrecked site where the black spike had penetrated and exploded in the floor.
But before he could examine the situation properly, another spike came flying right at him. Unlike the first time, Lumen expected this one and easily dodged it. At his current level he had gained something almost like a sixth sense and could sense incoming attacks before any of his other five senses could detect them. It was really a lifesaver in this case.
This was how he justified himself walking into this hall that clearly was filled with traps put there with the purpose of killing any intruders. But he got what he wanted eventually as the second spike gave him the general direction of where the spikes were coming from. He followed that trail and eventually came to a basketball sized hole in the wall.
