Pinnacle boss

Pinnacle bosses, also known as Pinnacle Atlas Bosses, refer to specific bosses that have their own boss zones (and usually have Atlas passive skills or Atlas keystones naming them directly). All pinnacle bosses except for the regular Elder encounter have an "Uber" variant that can be accessed with Uber fragments obtained from tier 17 maps. These variants have area level 85, introduce new mechanics, and the encounters are significantly harder in exchange for new and improved rewards.

Some Eldritch implicit modifiers have effects that only activate while "in the presence of a Pinnacle Boss".
