This new website for the game's relaunch is still incomplete.Legacy website
I was stating an example. Before you made your post 4 days ago about Cicatris, I have already done it. I am just frustrated that unfiltered websites had the answer to my search for the world boss instead of this site having it already.
'Mak'aal the Hellfire' spawns at the same location as Makin the Conflagrator (580, 880) in Scorched desert.
Spawning Makin you just got to kill 5 adds to get their orb to be absorbed, for Mak'aal you need to kill all the adds (~16) once all the orbs are absorbed Mak'aal will spawn. Watch out for his Caldera as it is lethal, me and a friend duo'd him easily as tank and DPS in ~100ipwr gear.
