The Chronomancer Julra is the challenging end boss of the Temporal Sanctum dungeon in Last Epoch, known for her complex mechanics centered around time manipulation and devastating area-of-effect attacks. She is a powerful Nagasa Priestess who has gone mad from studying the Eternity Cache, guarding access to this crucial crafting resource Last Epoch Gold.

Fight Mechanics and Strategy
Julra’s arena is circular with four harmful edges, forcing players to carefully manage positioning. The fight revolves around shifting between two eras—the Divine Era and the Ruined Era—using the Temporal Shift ability. This mechanic is essential to survive her most lethal attacks and to manage the battlefield effectively.

1. Temporal Shift: Players must switch eras to avoid Julra’s massive AoE nukes, such as the Catastrophic Implosion, which deals heavy Void damage and applies doom stacks. Timing your era swaps correctly is crucial to avoid instant death.
2. Dimension Tear: Each era shift leaves behind a dangerous Void damage zone called a Dimension Tear. These tears persist throughout the fight and restrict movement, so minimizing unnecessary shifts and avoiding stepping into them is key.
3. Pillars: Julra summons three pillars that behave differently depending on the era. In the Divine Era, they are destructible and harmless, but in the Ruined Era, they become invulnerable and unleash damaging lightning attacks. Players must switch to the Divine Era promptly to destroy these pillars before returning to the Ruined Era.
4. Healing Fountain: The boss summons a healing fountain that rapidly restores her health if left unchecked. Prioritizing its destruction is vital to shorten the fight.
5. Unraveling Decay: Rotating void beams sweep the arena, forcing players to find small safe zones and constantly reposition to avoid damage.
6. Additional Attacks: Julra also uses a variety of telegraphed attacks, including Frigid Tide (cold cone), Temporal Shot (void projectile), Chilled Seeker (homing cold projectiles), and Shocking Impact (lightning AoE).

Tips for Success
1. Stay near the edges of the arena to maximize space and avoid being trapped.
2. Use time shifts strategically to dodge her powerful attacks and to manage the pillars.
3. Focus on destroying healing fountains quickly to prevent prolonged fights.
4. Build high raw HP and consider cleanse abilities to mitigate damage-over-time effects.
5. Learn her attack patterns to anticipate and evade incoming damage effectively buy Last Epoch Gold.
