Advanced Cories are variants of Cori that spawn in the Skythern dimension.
Advanced Cories drop 0-2 Skythern Souls upon death. The maximum drop can be increased with Looting, for a maximum of 5 Skythern Souls with Looting III. Advanced Cories do not drop experience.
Advanced Coris are hostile to players and will attempt to attack them upon detection. In combat, Advanced Coris keep a distance from their targets and shoot projectiles towards them. When not in combat, Advanced Coris fly around randomly.
•Wearing Angelic Armor can allow you to get above the Cories, a valuable advantage.
•Using the Angelic Armor glitch, switching out armor to something like Mortum or better will let you survive at least 1 hit from a Cori.
•Approaching a Cori from above will allow easy hits on it and let you kill it, but while doing so watching out for other Cories above you is important.
•Making a base where you can seek refuge, take sniping shots with bows, phasers or blitzes (if you feel like wasting chunks on them) and if you are lucky enough then you should be able to clear a particular area of Advanced Cories in a matter of minutes.
