- Official description

The Hardest Solo PvM Challenge to date
The Inferno is a wave-based PvM challenge found at the core of the volcanic city of Mor Ul Rek. Only the most skilled adventurers will stand a chance of making it to the final wave, and even fewer will survive their encounter with TzKal-Zuk.

The TzHaar insist that outsiders must prove their strength before taking on the challenge of The Inferno. You must make a one-time sacrifice of a Fire Cape in order to convince the TzHaar you're worthy.

The Inferno will put you up against many new TzHaar enemies and will be a brutal test of skill. Mistakes will not be forgiven - so play carefully.

It is confirmed that logging out during waves will save your progress similar to the fight caves.
