One of the biggest complaints about Diablo 4‘s bosses is finally being addressed. Starting in Diablo 4 Season 10 Season of Infernal Chaos, Lair Bosses are finally getting changes to their invulnerability phases, allowing players with enough damage to bypass them entirely.
Lair Boss Invulnerability Changes
Thanks to community feedback, players can now completely bypass invulnerability phases if they beat a DPS check. Additionally, Lair Bosses‘ invulnerability phases can’t trigger until the fight has lasted longer than 10 seconds.
Once the boss loses 1/3 and again at 2/3’s HP, they will gain a shield for 5 seconds. If players manage to break this shield before those 5 seconds are up, they will skip the invulnerability phase. The first shield is equal to 1/3 the boss’s maximum HP, and the second is equal to 2/3 of the boss’s maximum HP.

A Great Change for Diablo 4
This is certainly an interesting change, yet for the most part, a rewarding one. By tying the invulnerability phases of bosses to a DPS check, players can bypass those stalling phases if their build is strong enough or if they know when to use their cooldowns.
Of course, players need to do this twice, with the second time giving the boss a shield just over 50% of their HP. So at times you might be able to bypass one invuln phase, but maybe not the second. Of course, if you can manage to skip both, that means your build is very strong, or you need to bump up to a higher torment.
Overall, this is a very good change for Diablo 4 as a whole. The community has expressed a growing frustration with every new season as new bosses like Andariel have lengthy fights, or some battles seem drawn out for very few drops. Despite the constant back and forth, there is proof that Blizzard is listening to the community. All we can hope for now is that they continue to do so.
