Boss Spoilers

His first attack is a wall of rocks and flying shields. Get high to avoid these
Next he will shoot bouncing balls and summon boulders from the ground. Note that the boulders locations are easy to predict. It is also highly recommended to use shield against bouncing balls - this way they will deal considerably less damage and disappear after one hit
His final attack is a charge where the boulders explode into flame.
Dantrest Medallion Right Piece becomes a 100% drop when a Condensed Chaos is used before interacting with the summon altar
