Diablo 4's Season of Infernal Chaos, which launched on September 23, 2025, shook up the endgame landscape with new mechanics, more punishing hordes, and smarter ways to farm Mythic Uniques. Whether you're grinding Torment tiers solo or leading a four-man squad, understanding the most efficient rotations, rift spawns, and crafting strategies is key to maximizing your loot and crafting potential. In this guide, we'll break down the most effective approaches to flood your stash with top-tier items and Diablo IV Items Resplendent Sparks, giving you the edge in the Season 10 meta.The Power and Appeal of Mythic UniquesMythic Uniques are not just another layer of loot; they represent the pinnacle of power in Diablo 4. At Item Power 800, they come with locked Greater Affixes and game-altering effects that can redefine entire builds. For instance, Harlequin Crest allows for cooldown resets that can turn a standard rotation into near-perpetual damage, while Tyrael's Might provides god-tier barriers, enabling survivability that can push even risky builds into endgame viability.Base drop odds from top-tier sources sit around 2%, but Season 10 introduces tweaks to caches and dungeon rewards, slightly nudging the probability upward. Salvaging duplicates yields Resplendent Sparks-essential currency for crafting and upgrading Mythics. Trading two Sparks at the Blacksmith guarantees a random Mythic cache, while the Vessel of Hatred combined with the Jeweler's Rune tab allows you to spend Sparks and Legendary Runes for precise crafting, giving control over your builds like never before.Torment Tier OptimizationIf you're pushing high Torment tiers, efficiency is key. Boss rotations are the bread and butter of Mythic farming. On Torment 4, top bosses have a minimum drop of seven Uniques per kill if approached correctly. Here are some essential tips for high-tier runs:Target Boss Volume Over Time- Rotate through bosses that spawn frequently and yield multiple Mythics. Prioritize chains like Belial, Lilith, and the new Bartuc spawn points.Exploit Rift Spawns- Chaos rifts now appear unpredictably, often yielding surprise Mythic drops. Always have a short-term travel route planned to intercept these rifts.Maintain High Kill Speed- Some Chaos Perks reward efficiency; the faster the kill, the higher the chance of bonus drops and extended duration for special seasonal buffs.By optimizing boss priority and rift engagement, you can consistently flood your inventory with high-value loot while minimizing downtime between kills.Resplendent Sparks and Crafting MetaResplendent Sparks have become a central currency for endgame progression. Salvage duplicates from Mythics and trade them wisely:Blacksmith Trade- Two Sparks yield a random Mythic cache, great for increasing overall Mythic volume.Targeted Crafting- Combine Sparks with Legendary Runes in the Jeweler's Rune tab to create specific items. This is especially useful for completing seasonal builds or filling gaps in meta-defining gear sets.The trick that's currently blowing up the Season 10 meta involves combining boss farming and Spark conversion. By maintaining high boss kill speed while simultaneously crafting selected Mythics, players can create multiple endgame-ready items per hour, giving a massive edge in Torment runs or competitive leaderboard farming.Solo Versus Group FarmingBoth solo and group farming have advantages. Solo runs allow for maximum flexibility and control over rift spawns, making it easier to target specific Mythics or Sparks. Group farming, especially four-player squads, maximizes kill efficiency and bonus drops. Coordinating rotations across Infernal Hordes or Chaos Waves ensures no Mythic is left behind.Solo Tip: Focus on high-density rifts and elite packs where Tornadoes, Bone Storm, or Chain Lightning effects can wipe entire rooms.Group Tip: Assign roles-tank, damage, crowd control-to maximize efficiency. This reduces downtime and ensures every drop is secured.Maximizing Loot VolumeTo maximize Mythic haul in Season 10:Stack Boss Rotations- Track spawn timers and rotate efficiently between top-tier bosses.Engage Random Rifts- Keep a mental or map-based note of rift locations; they're a significant source of surprise Mythics.Optimize Chaos Perks- Some perks extend kill speed or increase drop chance. Choose perks that complement your build and farming route.Salvage and Craft Strategically- Don't hoard duplicates. Convert them into Sparks and craft the Mythics you need for seasonal builds.By combining these methods, even solo players can achieve Mythic saturation in a single play session, ensuring every run contributes meaningfully to both gear and crafting resources.Conclusion: Dominating Season 10 EndgameSeason of Infernal Chaos introduces a dynamic and engaging endgame experience in Diablo 4.
