# Uber Pinnacle Boss PoE 3.18 added 7 new uber versions of Pinnacle Boss fights, accessible through Atlas Keystone Passives. These fights are extremely difficult, so only attempt them if you have a very powerful character. Six new keystones create uber versions of Path of Exile's pinnacle boss fights: Venarius, Sirus, The Maven, The Searing Exarch, The Eater of Worlds and The Shaper and The Uber Elder.

Like, really hard. Harder than saying goodbye to Zana hard. Only allocate these keystones if your character is extremely powerful and you know you can handle the challenge. In general, the encounters' rules are modified to be far more punitive and difficult. In return, though, you can earn some very enticing rewards. Each of the uber fights has an additional high-chance reward and a chance of getting a very very rare chase reward. For example, the Uber Maven guarantees an Elevated Sextant if you're able to complete the encounter. Very rarely, you may be able to earn an Awakened Exceptional Support Gem as well such as Empower, Enlighten or Enhance. These keystones unlock crazy battles that will challenge our most aspiring players who are deep in Path of Exile's endgame. They add a new level of difficulty for those who want to push their builds even farther than they ever have before.
