If you are searching for the definitive Trials of the Plague guide Eterspire veterans actually use, the short answer is this: hit level 160, enter the Infected Cavern via Sunfall Cave, and immediately begin stacking the new Plague Resistance stat. Update v75 completely rewrote the mobile MMORPG's endgame meta by introducing ranged enemies and deadly, dodgeable Area of Effect (AoE) attacks. You can no longer simply face-tank your way to best-in-slot gear.
Eterspire’s endgame has historically been a point of contention among its community. For months, reaching the level cap meant slamming your character against static, predictable encounters. You ground your way to 160, parked yourself in front of a boss like Raekar the Dark Lich, and prayed to the RNG gods for a drop. The Trials of the Plague shatter that paradigm, introducing dynamic combat mechanics and the game's first true deterministic crafting system. Here is exactly how to conquer it.
Core Strategy: A Definitive Trials of the Plague Guide Eterspire Players Can Trust
To understand the sheer impact of the Infected Cavern, you have to look at the journey required to get there. For most players, leveling a class from 1 to 160 is a blur of mainline quests up to level 50, followed by repetitive grinding in the Spire tower until level 116. From there, farming the Gloomy Cave snakes carries you to the level cap. This entire 160-level process quietly teaches players a bad habit: standing completely still and spamming your highest-damage ability.
The Trials of the Plague actively punish this learned behavior. The most disruptive change in the v75 update isn't just the health pools of the bosses—it's the accessibility and the required mobility.
Previously, Eterspire's progression was a rigid ladder. You needed specific lower-tier endgame gear to survive the next tier. The Trials of the Plague obliterate that bottleneck. There are zero prior endgame requirements to enter the Infected Cavern. If you hit level 160, you are ready to jump through the portal. This means new players can entirely skip the grueling Dark gear grind and immediately begin gearing for the current meta.
Navigating the Infected Cavern: Trials of the Plague Guide Eterspire
Accessing the new content is straightforward but requires venturing into hostile territory. The portal to the Realm of Everlasting War—specifically the Infected Cavern—is located deep within Sunfall Cave.
Once inside, you will immediately notice the shift in environmental design and enemy behavior. The cavern is a dark alternate realm where the Ancient War never ended, characterized by toxic green pools and decaying stone. More importantly, the enemies here are not strictly melee. Ranged mobs will pepper your party from a distance, forcing you to completely rethink your positioning.
The Luring Strategy
You cannot stand in the center of the trial room. Because waves now feature ranged mobs, standing in the open is a death sentence. They will attack you from 360 degrees, easily overwhelming your Guardian's ability to maintain aggro.

The prevailing strategy—pioneered by early access testers and endgame speedrunners—involves breaking line of sight. By pulling the wave toward the cavern walls or utilizing the entrance choke points, you force the ranged enemies to funnel into a tight cluster. This allows your Sorcerer to maximize their AoE damage output while the Guardian focuses their taunts on a single, highly manageable kill zone.
Boss Mechanics: Boliaph, Choh-Bih, and Vexren
The trials are split into three distinct encounters, each culminating in a fight against a devastating Plague boss. Unlike the static Remnant bosses of the past, these adversaries require active footwork. Glowing red telegraph markers will appear on the cavern floor moments before a massive AoE strike lands. If you fail to sidestep these markers, you will be one-shot.

Here is the breakdown of the three primary threats in the Infected Cavern:
| Trial Boss | Title | Primary Threat | Core Mechanic |
|---|---|---|---|
| Boliaph | The Infected | Vanguard Melee | Ranged Wave Spawns |
| Choh-Bih | The Scourge | Area Denial | Heavy AoE Telegraphs |
| Vexren | Source of the Plague | Apex Damage | Combined AoE & Adds |
Boliaph serves as the gatekeeper, testing your party's ability to handle the new ranged wave spawns. Choh-Bih escalates the difficulty by turning the arena into a minefield of dodgeable AoE attacks. Finally, Vexren, the Source of the Plague, combines both mechanics into a frantic DPS race where spatial awareness is just as important as raw damage output.
The Dust Economy and Plague Gear Sets
Historically, Eterspire relied entirely on raw, unforgiving drop rates. If you needed a specific helmet, you killed the boss hundreds of times until it dropped. The v75 update introduces "Dust"—a revolutionary bad-luck protection mechanic that fundamentally changes the endgame economy.

There are four new non-tradeable unique gear sets tied to this content:
- Bane Set: Drops from the first trial (Boliaph).
- Malady Set: Drops from the second trial (Choh-Bih).
- Blight Set: Drops from the third trial (Vexren).
- The 4th Set: Crafted exclusively using Dust.
Dust drops alongside the standard gear in all three trials. Once you accumulate enough Dust, you can manually craft the missing pieces of the fourth, ultimate endgame set. This deterministic progression means every single run pushes your account forward, even if you don't get a lucky gear drop.
These sets also introduce a brand-new stat element: Plague.
- Plague Resistance is your entry ticket. Without it, the ambient damage and specific boss mechanics will shred your health pool faster than your potions can heal.
- Plague Effectiveness dictates your clear speed, allowing you to efficiently burn through the massive health pools of the endgame bosses.
Class Roles and Party Composition
While it is technically possible to "solo" these trials by creating a solo party instance—provided you severely out-gear the content—it is deeply inefficient. The optimal setup is a balanced four-player team. Every class has a highly specific job to do when facing Vexren.

- The Guardian: Mandatory for their taunt. They must soak the initial burst, position the bosses away from the squishier party members, and hold the choke point during the luring phase.
- The Sorcerer: The undisputed king of wave clearing. Their AoE damage is absolutely required to handle the clustered ranged mobs efficiently.
- The Archer: Brings a crucial party-wide critical chance buff that significantly lowers the time-to-kill on high-health targets like Choh-Bih.
- The Rogue: Provides the raw, single-target burst damage needed to push bosses through their phase transitions before the dodgeable AoEs overwhelm the arena.
Additionally, every party member must bring a relevant Amulet to counter the Status Effects inflicted by the bosses. If your Guardian gets locked down by a status effect because they forgot their amulet, the ranged mobs will instantly pivot to your Sorcerer, resulting in a swift and embarrassing party wipe.
FAQ: Trials of the Plague Guide Eterspire
What level do I need to be to enter the Trials of the Plague? You must reach level 160 to enter the Infected Cavern. There are no other prerequisite quests or gear requirements to walk through the portal.

How do I get Dust in Eterspire? Dust is a new crafting material that drops from completing the Trials of the Plague. It is used to craft the fourth, deterministic tier of Plague gear, acting as a bad-luck protection system against poor RNG.
Where is the Infected Cavern located? The Infected Cavern is accessible via a portal located inside the Sunfall Cave.
