Gorgol warlord

In order you kill Gorgol Warlord, you must kill 2000 Gorgols required from Gorgol summoner.

Once you finish the task, go back to Gorgol Summoner and report the task.

Say: Hi, summon, yes, 1, yes.

After you get teleported to boss room, go towards the stairs and you'll find Gorgol Warlord waiting for you there.
