Final Room
Sam skillfully maneuvered around the shark and activated his energy vision.
He knew that there is some relation between the glowing tiles, their vibrating glows and the shark itself. And he is right, as always. The shark is being controlled by few of the glowing tiles. With the energy vision, he could also see that the energy concentration on tiles is different and right now, a set of tiles that have the same level of energy concentration are the ones creating this shark.
Sam dodged the shark attack and swam towards one of the tiles that is acting as the node for the shark.
He used the observation ability on the glowing tile and the tiles around it. The material is very much suitable to create formation nodes. He injected his own energy into the tiles around the glowing tile. Those tiles also started glowing, but it is different. They have a faint hue indicating Sam's control over those tiles.
