Grab the Red Orbs atop of the laser machine and activate the machine to collect the Artemis demon gun. Grab the Essence of Fighting and exit into the original room. It's best to use the Cerberus here to light those circular stones up quickly. Some Teleporters and some Collars appear after the first wave of enemies, so you may need a stashed Vital Star S to pass this if you get too hung up. You must light up both of the glowing circles before the enemies become vulnerable for death. Inside of here, walk over to the platform to activate the battle sequence. Go through the door and into the final doorway, the Trial of Fighting. You will be trapped by some Stone Dragons and Sandmen. This is a pretty tough Essence to collect. Keep zig-zagging and climbing the walls like a playful kitten to reach the Essence of Technique.

The key to doing this is to begin running from side to side and climbing the wall (towards the wall and the circle button) when the floor spikes begin thrusting upward.

Go through to watch a cut-scene, and get ready to endure an obstacle of dodging gigantic spears. The Trial of Techniques is next (the middle stairway).
