Zorxanth is a low-medium difficulty boss that can be found on planet Perceus in the Perceus System. It can be easily defeated with a small group and is notable for the vanquisher missiles that only come from him.
The boss itself is around level 72 and like it's variants in the Hydra and Cerebus systems is blocked off by about a dozen Phalinx and 2 Praetorianx.
While not hard for well geared players to clear solo it takes a bit of practice. Players wishing to fight him will find it more fun and much faster to kill as a group.
