Cublarc The Plunderer

Cublarc the Plunderer is the boss of Orc Marauders, which we can meet in 3 different circumstances.

THE GREAT ORCISH MARCH

A raid takes place about once a week along the riverbed on the Zao Steppes. Cublarc The Plunderer appears there 3 times always with the same waves - at 5, 18, and 30 minutes after the first announcement.
TIP: Don't be fooled! The raid does not end with the easternmost wave. After 5 minutes (and exactly after 30 minutes from the first announcement) a small wave will appear in the same place along with the boss, which some players do not know about, and leave the raid early losing the chance to kill the Cublarc.

ZZAION RAID

On this raid, we will meet only one Cublarc The Plunderer. It will appear with the opening of the gates to Zzaion (00:20: The gates to Zzaion have been breached! Orcs are invading the city!), but its respawn area is large and random. You can meet him both in front of the gates, where the raid has been held so far, and behind the gates, in the city of lizards.

RANDOM SPAWN

Not far from the ruined lizard city, east of the NPC Curos location, you can meet Cublarc The Plunderer, who appears there as a boss with a random spawn.
TIP: Check the larger area than on the map, as this boss may have gone unnoticed by players running using map-click, and gotten lured away a bit!
