How to Defeat Tchort Herald of Lilith in Diablo 4
Location:
Tchort is encountered during the "Fledgling Scholar" quest in Act I, within the Desecrated Archives of the Horadric Vault.
Preparation:
•Level: Ensure you're adequately leveled, ideally around the mid-teens or higher for a smoother fight.
•Gear: Have your best gear equipped, with health potions ready. Consider taking elixirs or using abilities that provide defensive or offensive boosts.
Fight Mechanics:
Arena Hazards:
There's a central vortex or whirlwind that can slow you down and deal damage. Avoid standing in or near this as much as possible.
Tchort's Attacks:
•Red Lightning/Projectiles: Tchort fires red lightning or multiple projectiles. These can push you back into the central hazard. Keep moving to dodge these.
•Fire Orbs: She creates fire orbs that explode with an area of effect. Watch for these and move out of their radius.
•Teleportation and Charge: Tchort can teleport to the edge of the room and charge or shoot charged bolts. This is her most dangerous move as it can push you into the vortex.
•Energy Waves: In later phases, she might push you around with lightning waves. Try not to get caught between her and the central vortex.
Phases:
•Phase Transitions: At health thresholds (like 25%), she might increase the intensity or number of her attacks, like creating more fireballs.
Strategy: 
•Stay Mobile: Constantly move around the outer edges of the arena to avoid both Tchort's direct attacks and the central vortex.
Attack Windows:
•Attack her when she's casting spells like the green wisps or when she's channeling energy into the orbs or the book. These are moments she's relatively vulnerable.
•When she stops to cast multiple projectiles or charge up for a big attack, this is your cue to either get in some hits or prepare to dodge.
•Avoid the Center: Always be aware of your positioning relative to the central vortex. Getting pushed or pulled into this can be fatal.
•Manage Resources: Use your strong attacks when you have a clear shot, then back off to manage your resources like mana or cooldowns.
Tchort Fighting Tips: 
•Dodge: Learning to dodge her teleport-and-bolt attack is crucial. Look for her telegraphing this move.
•Healing: Since there are no adds (additional enemies) to drop health potions, manage your potions wisely during the fight.
•Environmental Awareness: Use the pillars or any environmental elements to block or avoid her attacks when possible.
After Defeat:
You'll likely receive gear items, and you'll be able to interact with or collect the book, "Death Harnessed: Theories of Rathma," which progresses the story.
