Level 83+ Bosses:
Any Beyond Boss:
Difficulty: Medium.
Strategy: Run maps with high monster density to increase the chance of Beyond portals spawning a Beyond Boss. Focus on elemental resistances and damage output. Use online resources for specific Beyond Boss mechanics. (https://www.poewiki.net/wiki/Beyond_demon)
Any Delve Boss (Atziri, Xul the Patient, Uber Elder):
Difficulty: High – Very High (Uber Elder).
