Diablo 4 Season 10 Best Flay Barbarian Bleed Build Guide | How To Defeat Uber Lilith Fast?
Posted: Nov 18, 2025 Views: 21
Diablo 4 Season 10 will officially end on December 9th, but some players are still exploring the game and struggling with Uber Lilith.
Frankly, Season 10 has removed the immunity phase for each boss, significantly reducing the difficulty of defeating Uber Lilith. If you're having trouble killing it, you might just be lacking a suitable boss-killer build. Many builds can achieve this, such as Flay Barbarian build described below.

How To Play Flay Barbarian?
Main Skills
Flay is the primary damage source skill in this build. It stacks high amounts of Bleed by attacking enemies. You can easily stack billions of Bleed damage on Lilith.
Rupture is primarily a utility and finishing skill. Its role is no longer the main damage source. After gathering a large number of enemies and stacking Bleed, repeatedly using Rupture can quickly clear the area.
Additionally, when a boss's health is low, Rupture can quickly kill it. However, relying entirely on Rupture for damage in boss fights can be very painful, while Flay provides a much better experience.
Rage And Resource Management
One of the core mechanics of Flay Barbarian Build is maintaining a high level of rage. This is because Locran's Talisman provides Critical Strike Damage based on current rage. Therefore, keeping rage full is crucial.
The effects of Yul and Lum Runewords allow you to use skills with cooldowns to regenerate rage. Ring of Starless Skies reduces resource consumption; this combination allows you to focus on rage management during combat, as your rage will be continuously generated.
Defense
The core defensive skill of this build is Iron Skin, and its enhanced Tactical Iron Skin can be used when health is below 50%, providing healing and a shield. Aspect of the Iron Warrior further enhances the effects of Iron Skin.

How To Defeat Uber Lilith?
Uber Lilith is the most powerful boss in Diablo 4, but unlike other bosses, she doesn't provide a wealth of Diablo 4 items. While she appears to have a one-hit kill mechanic, in reality, aside from platform collapses, she doesn't have any truly lethal abilities. All her damage can be avoided through positioning and understanding the mechanics.
If your gear doesn't meet the above requirements, or you lack mythic items, you can try challenging Uber Lilith, but your damage will definitely be significantly lower, making it impossible to kill her before her phase transition.
Before challenging her, ensure your armor and elemental resistances are at their maximum, and your movement speed is at least 155%, which is crucial for dodging mechanics. You must have at least one ability that provides an unstoppable state. If you're using a Flay Barbarian build, War Cry and Wrath of the Berserker both provide unstoppable.
Remember to always prioritize dodging mechanics (especially waves), with damage output being secondary. When she releases waves, remember to stand at the bottom of the arena, and during the platform running phase, stay close to the edge to maximize your safety zone.
Note that when you reach the bottom or top of a platform, Lilith will perform a pull; you must use an unstoppable ability at this moment, otherwise you'll be pulled back to the center of the arena, making you extremely vulnerable to death. Keep moving throughout, especially when dealing with the triangular waves; remaining stationary is tantamount to death. However, if your damage output is high enough, you can definitely kill her before she transitions to her next phase.
This concludes the basic introduction to Flay Barbarian build and some key points for defeating Uber Lilith. If you consistently fail to defeat Lilith, it's best to upgrade your gear and damage before attempting the challenge again.
