SAO: HR - How to spawn Dar[] Intru[]er(Dark Intruder) for Fragrant Olive Sword Enigma

Here are requirements to spawn this Event Quest. 1. DLC 3 is completed and you have at least cleared first 10 Floors of 1000 Floors Singularity(AKA Oracle Remains, Infinite Dungeon). 2. Clear 2 Events: Windcutter and Extrapla[][]r Inva[]ers Note: I did attempt to spawn this Event before clearing first 10 floors and the Event didn't appear. The fastest way to get to Windcutter is to go to 4th Ouroboros Gate then turn around use the Teleporter to go back to Siobhan Eyrie.
