Crafting is a critical part of endgame gear optimization in Diablo 4, and lair bosses in Season 9 are a surprisingly efficient way to acquire rare materials like Grain of Anguish, Forgotten Soul, and Veiled Crystals.
Some bosses, notably Goremaw the Festering and Maazuun of the Deeps, are tied to drop tables that include these high-tier crafting components. Their consistent drops make them ideal targets for players looking to reroll gear stats or Diablo 4 gold forge ancestral-level enhancements.
The benefit of these bosses over dungeon farming is time efficiency. While Nightmare Dungeons can be lengthy, lair bosses offer quick, direct encounters with guaranteed material payouts when killed under the right conditions (e.g., cursed lair affixes or seasonal modifiers).
Many lair bosses also drop exclusive crafting recipes, especially during seasonal events. These recipes often include new item upgrades, sigil crafting variations, or glyph enhancement options that cannot be found elsewhere.
Enhance your material gain by equipping loot-boosting aspects or elixirs before engaging the boss. Salvaging dropped rares and legendaries post-fight is also a smart way to stockpile Veiled Crystals or Arcane Dust.
Some lair events offer material multipliers when completed within a time limit or under a boss enraged condition. Monitor these mechanics closely and sell diablo 4 items plan builds that can burst bosses quickly to capitalize on these bonuses.
For players aiming to fine-tune their builds through crafting, lair bosses represent a repeatable, efficient, and underutilized resource in Season 9.
