Soul Meld

The Soul Meld is a manifestation of souls that have long been tormented and used by the Scholars. A powerful Scholar tried to manifest a soul energy that had never been tried before, leading to a powerful discharge, releasing all of the spirts used in the disaster. The spirits use the body of the now deceased Scholar to manifest in the world.

Battle
The player would stumble upon an exit to the Westbound Sanctum, and walk towards it. Before reaching the exit door, a chandelier would crash down from the ceiling and hit the player, crashing both through the floor. When the player wakes up, they'd be in a room full of Scholar artifacts, including books in the background that would mysteriously flip a page occasionally. Once the player reaches a large room, both doors to the room would lock and a body would fall on the ground. It would then levitate and shift into the boss. Throughout the battle, the lower the bosses health gets, the more damaged the Scholar corpse will appear.


 * Twirl Shot - A ghost would shoot out of the corpse, swirling in twirls before coming to a stop, exploding into several smaller souls that shoot outwards.
 * Swipe - One of the ghost hands holding up the corpse would release and swipe at the player. If it grabs them, it'd hold them and throw them at the farthest wall, dealing double damage.
 * Dive - The ghost hands would throw the body on the ceiling and then toss it down onto the player, grabbing it just before it hits the floor and resuming normal stance.

Phase 2
Around about half health, the boss would reach phase 2, and the Scholar corpse would crumble onto the ground. A giant phantom figure with many arms and legs, appearing as an amalgamation of several dozens of souls, would appear above it. As the boss takes damage, soul will slowly start to leave it, causing it to appear smaller and less complex.


 * Drill - The boss would spin at the player, ramming towards their side of the room.
 * Quad Twirl - Exact same attack as the Twirl Shot, but four spirits would do it at the same time, with the explosion from each happening slightly after the other.
 * Slam - The boss would reach their hands out and smack the ground, slowly moving their hands out each smack until the walls of both sides have been reached.
 * Desperation - The boss starts throwing itself at the player when they have been defeated. They'd repeat this process several times, before eventually exploding into several souls, who all would ascend.

Conclusion
After defeating the boss, the souls that ascend upwards would unknowingly release a chain that the player can climb up. Upon climbing up, you reach the exit of the building. After leaving the Westbound Sanctum, the building would shake and collapse down a little ways. The player would then go back into the Sanctum and be required to climb to the top, which is now available.
