Structure of the Kurast Undercity
The dungeon consists of three levels, each with Diablo 4 Gold distinct mechanics:

1. Timed Floors (Levels 1 & 2)
Players must clear enemies, complete objectives, and activate braziers before time runs out.
The Attunement system tracks progression, rewarding higher loot tiers for faster clears.
Braziers serve as key objectives—activating them spawns enemies, grants bonus time, and significantly reduces cooldowns.
2. Boss Arena (Level 3)
The final level features a boss battle that is not timed.
Boss mechanics are similar to Nightmare Dungeon bosses, with telegraphed attacks and stagger phases.
Once the boss is defeated, a reward chest is unlocked, with loot modified by Tributes and Blessings.
Key Mechanics
1. Attunement System
Attunement measures your performance within the dungeon, rewarding higher tiers of loot.
Completing objectives, killing elite enemies, and activating braziers increase Attunement.
Attunement Tiers:
I – Base Rewards
II – Moderate Loot Increase
III – High Loot Increase
IV – Maximum Chest Rewards
Tip: Aim for Attunement IV by prioritizing objectives and defeating all major enemies.

2. Braziers – Timed Objective & Cooldown Reduction
Found throughout Levels 1 & 2, braziers are activated to spawn enemy waves.
Defeating the enemies grants bonus time and cooldown reduction.
Optimizing your route to activate multiple braziers quickly is crucial for higher Attunement rewards.
3. Boss Mechanics
Each run ends with a boss battle that is not timed.
Bosses have unique abilities, area-of-effect (AoE) attacks, and stagger mechanics.
Staggering the boss opens a damage window, increasing kill efficiency.
The final chest drops loot based on Tributes and Blessings.
Maximizing Rewards: Tributes & Blessings
Tributes – Customize Your Loot
Tributes are consumables offered at the Spirit Brazier before starting a run.
They modify loot drops, increasing the chance for Runes, Ancestral gear, and D4 Gold Mythic Uniques.
