Forget Apparition Incursions after hitting Torment 1—Lair Bosses are the backbone of efficient Spectral Ash and loot farming. Here's how to build a seamless farming loop:
Helltides are packed with Whispers, chests, and enemies, dropping Living Steel, Exsanguinated Blood, and other boss-summoning materials. Prioritize Whisper events and open chests for maximum efficiency. Use Elixirs (8% XP boost) to speed up progress. Blood Maiden fights are tough early on, so wait until Torment 2 or 3 to tackle her for extra rewards.
Teleport to Lair Bosses like Lord Zir, Grigoire, or Varshan using your Helltide materials. Each kill drops 100–200+ Spectral Ash (more on Torment 3–4), alongside Uniques and Tributes of Titans. You don't need keys to claim Boss Powers—just kill them once on Torment 1 to unlock their power. For example, a Torment 3 Lord Zir kill can yield 140 Spectral Ash from the loot hoard, scaling higher on Torment 4.
Tributes of Titans act as keys for Kurast Undercity runs, granting Lair Boss hoard caches. These caches drop more Spectral Ash, boss materials (Living Steel, Malignant Hearts), and high-tier gear. This keeps your loop self-sustaining, reducing reliance on Incursions.
Some Lair Bosses, like the Harbinger of Hatred, count as Whispers. Kill them without claiming loot to earn 5 Favor for the Tree of Whispers, which rewards caches with gear and materials. This adds another layer of rewards to your boss kills.
Boss Powers: Unlocking and Upgrading
Boss Powers are critical for boosting your build, and Season 8 makes them easier to unlock:
Unlocking Powers: As soon as you reach Torment 1, kill each Lair Boss (Grigoire, Varshan, Lord Zir, etc.) once to unlock their Boss Power—no loot key required. For Belial's power, complete the questline to fight Uber Belial. Ashava's Poison Breath is the standout, trivializing levelling with Dot builds like Whirlwind or Blight.
Upgrading Powers: Spectral Ash is used to rank up powers, with level 20 requiring thousands. Spread upgrades across multiple powers to meet Season Journey goals (e.g., four powers to rank 12). Avoid dumping all Ash into one power early on, as this limits your ability to farm Uber Belial for top loot.
Must-Have Power: Ashava's Poison Breath synergizes with damage-over-time skills, making it a game-changer for levelling and early Torment tiers.
Loot Bonanza: New Boss Drop Mechanics
Season 8 revamps boss loot, making Lair Bosses a goldmine for Uniques and Mythics:
Mixed Loot Pools: Bosses now drop their specific Uniques (e.g., Lord Zir's Cruor's Embrace) and general Uniques (e.g., Varshan's Bloodless Scream, Beast in Ice's Ring of Mendeln). This increases your chances of scoring build-defining gear.
No Summon Materials Needed: You can summon bosses for free, though keys (from materials or Tributes) are needed to claim loot. Farm Torment 1 for powers, then use keys on Torment 3–4 for better drops.
Season Journey Boost: Completing Season Journey Chapter 2 grants two Smouldering Ashes, boosting Belial's spawn rate after boss kills. Without these, Belial is rare (e.g., 0 spawns in 30 boss kills). Chapter 3 likely grants two more Ashes, further increasing spawns.
Tip: Farm Torment 3 for reliable boss kills until your build can one-shot Torment 4 bosses, as the loot difference (6–7 items) isn't worth the struggle early on.
Mercenaries: Boosting Your Farm
Mercenaries enhance your farming efficiency, especially for boss materials:
Subo (Priority): Level Subo's reputation to add boss-summoning caches to the bartering pool. Restock supplies with Den Coins (e.g., 400 coins for a cache) to gain extra Living Steel or Malignant Hearts.
Varana: Unlocks Masterworking material caches, complementing Subo's rewards. Level both to expand your bartering options from 5 to 10–12 choices.
How to Level: Kill Lair Bosses and complete Apparition Incursions to raise Unveiled Oath rank, which boosts mercenary reputation. Boss kills (including Blood Maiden) count toward this, making your farming loop even more rewarding.
Pit and Endgame: Managing Expectations
Torment 4 and high Pit tiers are significantly more brutal in Season 8, requiring billions of damage to clear efficiently:
Torment Difficulty:
Torment 1–2: Easily cleared with basic gear (e.g., Summer Necromancer, no aspects).
Torment 3: Bloodwave Necro deals 2–3 billion damage, one-shotting bosses.
Torment 4: Bosses need 900 million–1 billion+ damage per hit, with high survivability (10,000+ HP). Unoptimized gear leads to one-shot deaths.
Pit Scaling: A Bloodwave Necro with shoddy gear (6–8 Masterworks) hits for hundreds of millions at Pit 70. Reaching Pit 100 requires 10–30 billion damage, so don't stress if you cap at Pit 75–80. Even top builds may max out at Pit 130–140 due to nerfed scaling.
Mindset: Don't obsessively chase Pit 100. Pit 70 is respectable, especially for non-S-tier builds like Corpse Explosion, which can't compete with Bloodwave's overpower scaling.

Ashava's Poison Breath is overpowered for Dot builds (Whirlwind, Blight), making levelling and early Torment tiers a breeze.
How do I increase Belial's spawns?
Complete Season Journey Chapter 2 for two Smouldering Ashes to boost Belial's spawn rate. Chapter 3 likely adds two more.
What's the best build for this farming loop?
Bloodwave Necromancer is top-tier, dealing billions of damage to clear Torment 3–4 bosses and Pit 70+ with ease.
