In a rather confusing twist of D2R Items things, Lord Martanos seems to spawn every 30 minutes. While that should mean his spawns occur every 30 minutes in a formal hour (so 7:00, 7:30, 8:30, etc.) there is a chance that his timer can be just a bit off every now and again. If you stay in this location for a while you'll be notified that he's been appeared.

The battle against Martanos isn't especially difficult with respect to similar Diablo Immortal bosses. His health pool is incredibly vast, however provided you've got a little help from a handful of other players, you are likely to be able to take the boss down with basic attack and defensive strategies. It's even possible to solo him if you're powerful enough (though it's rare and will likely take long).

While Lord Maranos may drop a variety of random rewards, the thing that's most important to you is his guaranteed reward one of his Zakarum Sigils. What is so significant? It's because they help you make the difficult fight with the Ancient Nightmare just a touch more manageable.

In the beginning, it's important to know you can only find the Ancient Nightmare can only be found every Wednesday and Friday at 12 pm at 8:30 pm, 12 pm, and the last one is 10pm (local Server time) D2R items cheap. If you're trying to search for the boss any other time you'll be very disappointed by the things you don't discover.
