One of the night sorceries of Sellia, Town of SorceryLandmark. Makes the caster semi-invisible. While on horseback, effect extends to cover the mount. This sorcery can be cast while in motion. The Sellian assassins considered every option that aided their dirty work.

Altus PlateauGrace at the top of the Tower after completing the Mirage RiseLandmark puzzle. When you reach at the location, although your map marks there is a tower, you will notice that there is nothing there. However, you will receive a map, called Mirage Riddle. You will have to interact with three Phantom crests. The first one is next to that initial position, hard to miss. The second one can be found by continuing to the west, near the rock wall. Enemies will spawn. The final one, is near the Bower of BountyGrace site of grace. Starting at the Bower of BountyGrace site of grace, head directly south to the edge of a cliff. Here a small enemy will spawn. Once you see this enemy, head east along the cliffside. On the left side you will see a strange looking stone which you have to hit in order to reveal the phantom crest. The stone lies before the bridge and will likely have messages surrounding it. Once you found all three, head to where the tower was supposed to be, to actually find it this time. Climb all the way to the top to find this sorcery, along with Unseen Blade and x5 Slumbering Egg.
