With each Diablo 4 season, class viability shifts due to balance patches and new systems. In Season 9, the addition of Horadric relics and Echo variants introduces new build opportunities. Here's how each class can best take advantage of the new seasonal mechanics.

Barbarian players benefit heavily from Diablo 4 Items relics that trigger effects on damage-over-time. Combining Bleed with Thorns via Wrathful Echo relics turns them into juggernauts. Pair this with unstoppable effects for ideal synergy.

Druids now excel with nature-based relics that boost elemental effects. A Storm/Werebear hybrid with lightning damage relics performs well in both solo and group content. Wolf companions also benefit from relic enhancements.

Necromancer gets a revival with minion-centric builds that utilize relics enhancing summons' critical damage or health regen. With certain Echo bosses targeting the summoner, relics that grant defensive buffs upon minion loss are crucial.

Sorcerers thrive with elemental amplification relics. Fire builds especially shine this season due to relics that increase DoT duration and chain reaction effects. Additionally, teleport cooldown relics make them more mobile in chaotic encounters.

Rogues remain top-tier, especially with trap-centric setups. Traps now scale with utility relics, enabling higher burst and lower cooldowns. Poison builds get another buff via stacking relics tied to affliction multipliers.

Class balance is tighter this season than Diablo 4 Items buy in previous ones, meaning most builds are viable when synergized with relic slots. Build diversity is encouraged, and experimentation is heavily rewarded.

If you're unsure which class to play, consider your preferred playstyle—whether melee sustain, ranged burst, or hybrid control—and pair it with Season 9’s relic pathways that complement those mechanics.
