Blizzard reduced the experience awarded for World and Lair bosses in Diablo IV’s 2.6.0 patch, a change listed in the official patch notes for Build #70982 dated March 11, 2026. The notes include a single line under Miscellaneous: “Experience rewards have been reduced for defeating World and Lair Bosses.” Blizzard did not attach further explanation in the published notes.
Players noticed the change after Season 11 spawned an efficient, if controversial, leveling tactic like certain world and lair bosses, notably Azmodan, could be defeated very quickly by large groups while participating characters remained largely inactive and still received full experience. That behavior made the events attractive for passive XP gains on alternate characters.
Blizzard has not said the reduction targets that specific tactic, but the adjustment will make boss events a less lucrative source of passive experience. With Season 12 starting soon alongside the 2.6.0 update, players looking to level new characters will likely depend more on activities such as Helltides, Nightmare Dungeons, or seasonal content.

Patch Notes, Diablo IV 2.6.0 (Build 70982)
The following item appears in the official patch notes published by Blizzard for the 2.6.0 build scheduled March 11, 2026.
- Experience rewards have been reduced for defeating World and Lair Bosses.
How much this will slow broad leveling speeds remains unclear; the note is short and lacks numerical detail. The change could still leave some XP value on boss kills while reducing the appeal of farming them passively.
