Guide to Helliquary & Weekly Vaults: Rewards, Strategy & Best Practices

The Helliquary and Weekly Vaults are two of the most important systems in Diablo Immortal for players who want consistent gear upgrades, rare crafting materials, and long-term power progression.

These features are not just side activities; they’re integral to maximizing your character’s combat rating (CR) and overall efficiency in high-level content.

Whether you’re a solo grinder or part of an active clan, understanding how to fully exploit them can make the difference between slow progression and dominating every PvE challenge the game throws at you.

Understanding the Helliquary

The Helliquary is a unique feature unlocked early in your mid-game journey, designed as a boss challenge system. Unlike dungeons or rifts,

Helliquary bosses are tailored encounters that test both your mechanical skill and raw power. They drop Scoria, a special material used to upgrade your Helliquary, and sometimes offer Demonic Remains—permanent power boosts that increase your CR across all activities.

Every boss has unique attack patterns. Some require precise movement, others demand burst damage phases, and a few test your survivability under constant pressure.

Beating them is not just about raw stats—it’s about learning the fight, optimizing your build, and timing your cooldowns perfectly.

The Helliquary isn’t static. As you progress through higher difficulty tiers, you’ll unlock more powerful bosses, each offering greater rewards. The upgrades gained here impact nearly every activity in the game, making it a core part of endgame progression.

The Role of Scoria and Upgrades

Scoria is the lifeblood of your Helliquary upgrades. You can acquire it from Helliquary bosses, Challenge Rifts, certain events, and sometimes as drops from rare encounters.

Once collected, it must be purified at Charsi, turning it into Refined Scoria. This refined form is then used to level up your Helliquary, granting significant combat rating boosts.

It’s important to schedule your Scoria farming strategically. Since Weekly Vaults and some events have time-gated rewards, aligning your Helliquary upgrades with these cycles ensures you’re always at peak power for your next fight.

Weekly Vaults – How They Work

Weekly Vaults are a treasure chest of high-value rewards, tied directly to your clan’s activities. They function as a reward storage system for loot gathered during Immortal and Shadow activities. The catch? You must claim them before the weekly reset, or they’re gone forever.

To access the vault, you often have to engage in the Vault Raid mini-event. This isn’t a simple “walk in and grab loot” task—defenders may try to stop you.

As an Immortal, you’re protecting the vault from raiders. As a Shadow, you’re trying to steal from it without alerting the defenders. This creates a thrilling PvPvE experience that blends strategy, stealth, and combat.

The rewards inside the vault can include Legendary Gear, set items, gold, Hilts, and even rare crafting materials. They scale with your level and performance, making it critical to participate weekly.

Rewards Breakdown

While the exact loot can vary based on your role and activity level, here’s what you can generally expect:

• Legendary Gear – Perfect for filling in build gaps or salvaging for upgrade materials.
• Set Items – Essential for min-maxing endgame builds.
• Scoria – Directly fuels Helliquary upgrades.
• Gold & Hilts – Useful for shop purchases and crafting.
• Random Upgrade Materials – Including Enchanted Dust, Glowing Shards, and Scrap Materials.

Maximizing rewards isn’t just about participation—it’s about timing. Enter the vault at peak clan activity times to ensure better raid outcomes.

Strategy for Helliquary Bosses

Tackling Helliquary bosses efficiently requires both preparation and execution:

• Gear Optimization – Prioritize high-CR gear even if the stats aren’t perfect. CR is king for boss entry requirements.
• Skill Loadout – Adapt your skills for the fight. If a boss has high burst phases, lean into damage cooldowns. If survival is the challenge, bring shields and healing abilities.
• Learn Mechanics – Many bosses telegraph their most dangerous attacks. Recognizing these cues can save you from wipes.
• Consumables – Stock up on health potions and buffs before attempting higher-tier bosses.
• Group Coordination – For tougher fights, run with a dedicated team. Having a tank, healer, and consistent DPS makes a huge difference.

Best Practices for Weekly Vaults

Maximizing your Weekly Vault gains requires discipline:

• Participate Early – Don’t wait until the last day. Unexpected clan inactivity or PvP losses can lock you out of rewards.
• Coordinate Raids – If you’re a Shadow, plan raids when defenders are distracted. If you’re an Immortal, set defensive teams during peak raid hours.
• Track Reset Times – Vault rewards vanish after the weekly reset, so claim them on time.
• Leverage Communication – Use your clan’s voice chat or text channels to coordinate strategies in real time.

Combining Both Systems for Maximum Gain

The Helliquary and Weekly Vaults complement each other. The CR boosts from Helliquary upgrades make Vault raids easier, while Vault rewards—especially Scoria—feed back into Helliquary progress.

By syncing your weekly schedule to hit both systems, you create a feedback loop of power growth.

A common high-level approach is to run Helliquary bosses early in the week, secure Scoria for upgrades, and then hit Vault raids when your CR is at its peak. This not only increases your chances of victory in PvPvE encounters but also ensures your rewards are consistently improving.

The Long-Term Payoff

Players who ignore these systems often hit a CR wall in higher-end content. By contrast, those who actively engage with both the Helliquary and Weekly Vaults will notice steady, compounding gains.

Over time, these advantages snowball, letting you take on higher-tier raids, climb leaderboards, and dominate in PvP.

The grind is real, but the rewards are worth it. Every week spent optimizing these systems brings you closer to endgame mastery.
