DRG Rogue Core Upgrade Guide: Expenite, Tiers, Best Picks

The DRG Rogue Core upgrade system looks simple in the first two floors: mine Expenite, deposit into the R.E.P.D., pick something from the menu. By floor five, players who treated every selection as a free-standing decision are hitting walls that players who understood the cost curve saw coming.

The DRG Rogue Core upgrade economy isn't hard to understand once you know how it works. Most players never read it. That gap is where runs end.

TL;DR: Expenite powers the R.E.P.D. upgrade device. First upgrade: 120 Expenite. Each subsequent: +10, capping at 230 before exponential scaling. Expect ~12 events per player per full run. Six tiers: Common through Artifact. Artifact picks like Glass Cannon (+150% damage, -90% health) can redefine a run or end it, depending on your Enhancement deck state. Per-class priorities: Guardian wants stun extension, Slicer wants kill-chain, Falconer wants charge speed, Spotter wants mark duration, Retcon wants Rage window + second Time Rewind charge.

DRG Rogue Core upgrade system: quick answer

The DRG Rogue Core upgrade loop runs on Expenite, a mineral you mine while descending Hoxxes IV. Deposit enough into the R.E.P.D. terminal and it triggers an upgrade selection event. The cost structure is fixed: 120 Expenite for the first upgrade, then +10 per subsequent upgrade until the price caps at 230, after which it scales exponentially. A typical full run gives each player roughly 12 DRG Rogue Core upgrade events.

In co-op, each of the four players gets 6 options per event, drawn from a shared pool and selected in random order. When one player picks, that option disappears for everyone else. Health Reward is the exception: it always appears in the final slot and is available to every player regardless of pick order.

The DRG Rogue Core upgrade deck (Enhancements) you build during a run resets completely when the run ends, win or lose. Meta-progression, what carries over between runs, is a separate system that's limited in the Early Access build. The upgrades you pick in a run are temporary; the skill in picking them is permanent.

How Expenite flows: pacing your upgrade events

Expenite spawns in veins embedded in cave walls. Mining speed and route efficiency determine how many events you trigger per floor. On floors 1-3, Expenite is dense and events trigger frequently. By floors 7-10, the cost curve has hit 230 and each event requires meaningfully more time to fund.

That cost escalation matters for DRG Rogue Core upgrade planning: the first three floors are where you establish build direction, the later floors are where you execute it. A Common upgrade on floor two that doesn't fit your class's core mechanic isn't the end of the world. An Uncommon on floor seven that conflicts with your Legendary pick from floor five is a genuine setback.

Don't save Expenite. The cap at 230 means banking beyond one event's threshold wastes potential events. Mine forward, deposit when you hit the number, and take the event even if the options feel mediocre. A weak upgrade is better than a delayed good one.

Decide your upgrade direction by floor two. Which of the six tiers you're aiming for at the Legendary level determines which Rare and Epic picks are worth taking along the way. Running unfocused through the first four floors, taking whatever looks good, usually produces a deck that's weak exactly when the game stops being forgiving.

DRG Rogue Core upgrade tiers: Common to Artifact

Common: Incremental improvements to base output. More damage, slightly wider area, marginally faster cooldowns. Common picks are never exciting but they're always correct when Rare options don't fit your build direction. A Common that amplifies your signature ability is worth more than an Uncommon that doesn't interact with it.

Uncommon: Start adding secondary mechanics. An Uncommon might add a damage-over-time component to a class that normally deals burst, or introduce a cooldown interaction that changes timing patterns. Uncommons are where build shaping begins, but the effects are still incremental.

Rare: Reshaping starts here. Rare Enhancements often introduce a new mechanic entirely rather than upgrading an existing one. A Rare might add a second instance of Guardian's fear zone at half the stun duration, or give Slicer's Plasma Blade a bleed effect that persists after the kill chain ends. Taking a Rare that conflicts with your existing deck is a pivot; taking one that extends it is a compound.

Epic: The turning point. Epic Enhancements produce effects strong enough to define the rest of the run's priorities. An Epic that doubles Spotter's crit window duration means every subsequent pick should build toward keeping targets marked. An Epic that adds a third Retcon Rage charge changes the risk calculus for the rest of the descent. By the point you're buying Epics, your deck should have enough direction to evaluate the Epic against what you already have.

Legendary: Run identity. Legendary picks are rare enough that most runs see one or two. They typically combine multiple Rare-level effects into a single slot and create combinations with your existing deck that didn't exist before. The pool is large enough that you won't see the same Legendaries twice in consecutive runs.

Artifact: Extreme upside, explicit cost. Artifacts are the tier Ghost Ship designed around deliberate imbalance. They can't be stacked with other Artifacts. Most of them have a negative component that restructures how the run plays.

Artifact-tier picks appear at any point in the run. The stat tradeoffs are stated clearly. Whether your current deck survives the cost is the actual question.

Artifact picks: when Glass Cannon works

Glass Cannon is the most-discussed Artifact in Rogue Core's first week: +150% damage at the cost of -90% maximum health. The math looks terrifying. The application is narrower than players assume.

Glass Cannon works when you have a defensive layer that isn't health-dependent. Guardian with Seismic Gloves covering crowd control: stun the wave, kill in the window, take zero hits. Retcon with Time Rewind charges: the ability rolls back damage, and at 10% max health you need Time Rewind timed correctly rather than frequently. Falconer in a squad where the Lightning Drone's remote revive means a downed Glass Cannon player is back in five seconds rather than gone.

Glass Cannon fails when taken without those layers. A Slicer who takes Glass Cannon on floor three with no defensive Enhancements is gambling on flawless play through however many floors remain. The chain bonus helps. It doesn't help enough to survive an unavoidable hit at 10% health.

The other confirmed Artifacts in the EA build include Extreme Vigor (aggressive passive regeneration: relevant for tanking strategies) and others focused on speed, cooldown reduction, and ability amplification. Around 25 distinct Artifact modifiers were documented in the first week of Early Access by the community. Not all of them are available every run: the pool rolls randomly each event.

Taking a DRG Rogue Core upgrade at Artifact tier isn't a mark of expertise. Taking the right one for your current deck state is.

Per-class upgrade priorities

The DRG Rogue Core upgrade priorities differ meaningfully by class because each signature ability creates different value from Enhancement interactions.

Guardian prioritizes Enhancements that extend Seismic Gloves stun duration or increase the munition count from the 12-charge base. Secondary priority: Enhancements that add residual area damage after the fear zone fades. Skip damage multipliers that don't interact with the Seismic Gloves signature. Guardian's base weapon damage isn't its primary contribution, and building toward it sacrifices the crowd control role that the class exists to fill.

Slicer targets kill-chain extension and chain trigger reduction. Enhancements that let chains restart on a shorter kill interval expand which rooms Slicer can chain through: a hallway with sparse enemies is a chain-dead zone without an Extension pickup. Blade damage multipliers compound with the kill-chain bonus and are efficient at any tier early. In co-op, chain duration Extension matters more than flat blade damage because teammates' kills can contribute to chain maintenance if Slicer has the right Enhancement active.

Falconer wants charge replenishment rate and burst count per charge. The Lightning Drone's 5-charge pool with 10-second replenishment is the baseline; Enhancements that reduce replenishment time or add a charge multiply how often the revive and electrocution are available. The arc damage Enhancement, which adds shared arc damage to electrocuted targets hit by additional bursts, is the strongest Falconer pick in dense wave scenarios. In a group of six enemies sharing electrocution, one drone charge hits them all through the arc.

Spotter treats mark duration and charge count as the highest-priority stats. Crit Darts' +100% crit chance runs for 5 seconds per mark on a 3-charge, 18-second cooldown. Any Enhancement extending mark duration is multiplied by squad size in co-op: a 3-second extension across four players produces 12 additional player-seconds of crit output per use. Charge count additions let Spotter keep more targets marked simultaneously in multi-group encounters.

Retcon has two distinct upgrade paths that diverge at the Rare tier. Rage-focused builds want window duration extensions and Rage damage multipliers: a 2.5x Rage with three damage Enhancements produces burst output that other classes can't approach. Rewind-focused builds want a second Time Rewind charge per cooldown cycle, which turns the class from a single-lifeline design into a layered defensive tool. Both paths work. The mistake is half-investing in both. Pick a direction by the time you're buying Rares.

Enhancement deck strategy in co-op

Four players each picking independently creates a coordination problem most squads don't address until they've lost runs to it.

Assign upgrade priorities before the run starts, not mid-event. One player focuses on damage amplification Enhancements for whoever the squad's burst handler is. One player takes cooldown reduction Enhancements, specifically relevant for Retcon if someone's running Time Rewind as the squad's defensive anchor. At least one player takes a healing Enhancement, because passive recovery compounds across ten floors and floor damage is unavoidable.

Know the pick order implications. Players who pick early in an event get the widest option pool. Players who pick last get whatever's left. If your squad has a Glass Cannon Slicer who needs a specific Legendary to make the build viable, picking last means hoping the pool still has it after three other players have made choices. Pick order is random each event. High-variance builds belong to players comfortable with having their plan disrupted.

Don't overlap Enhancement categories. Two players stacking the same type produce diminishing returns while the squad's gaps go unfilled. A squad where three players take damage Enhancements and no one takes survivability is efficient against floor three. It collapses against floor eight when enemy density starts punishing exactly the hole you left open.

Four players picking from a shared pool means one player's choice removes options for everyone else. Discuss priorities before the run, not mid-event.

Meta-progression: what carries between runs

In the Early Access build, meta-progression is limited. It primarily unlocks starting options and minor starting bonuses, affecting what you begin a run with rather than how it develops. The DRG Rogue Core upgrade deck resets completely at run end regardless of outcome.

Ghost Ship has confirmed that the meta-progression layer will expand significantly before 1.0. Based on the studio's approach to the original Deep Rock Galactic, expect the full release to include unlock trees for each class, starting bonuses tied to specific upgrade paths, and possibly account-level multipliers for Expenite generation.

For EA, treat meta-progression as onboarding rather than strategy. What you unlock affects your starting position marginally. The knowledge you build about how the DRG Rogue Core upgrade curve works, which Enhancements fit your class's signature ability, and when to take Artifact-tier picks: that doesn't reset. That carries.

Key takeaways

• Expenite powers the R.E.P.D. upgrade device: first pick 120 Expenite, +10 per subsequent upgrade up to 230, then exponential
• Expect ~12 upgrade events per player per full run; don't bank Expenite past one event's threshold
• 6 tiers: Common (incremental) through Artifact (extreme modifiers with explicit costs)
• Artifact picks like Glass Cannon work with defensive layers already in place; they fail without them
• Guardian: stun extension and munition count. Slicer: kill-chain extension and trigger reduction. Falconer: charge rate and arc damage. Spotter: mark duration and charge count. Retcon: commit to Rage or Rewind by Rare tier.
• In co-op, assign upgrade priorities before the run. Pick order is random. Overlapping Enhancement categories wastes potential.
• Meta-progression is limited in EA. Build knowledge, not account stats.

Frequently Asked Questions

How does the upgrade system work in DRG Rogue Core? Mine Expenite while descending, deposit into the R.E.P.D. device to trigger upgrade events. First upgrade costs 120 Expenite, each subsequent pick costs 10 more, up to a cap of 230 before exponential scaling. About 12 events per player per full run. In co-op, four players each get 6 options per event, selected in random order from a shared pool.

What are the 6 upgrade tiers in DRG Rogue Core? Common, Uncommon, Rare, Epic, Legendary, and Artifact. Common and Uncommon improve base kit. Rare and Epic reshape playstyle. Legendary defines the run. Artifact has extreme positive effects with explicit penalties like Glass Cannon's -90% max health. Artifacts can't be stacked.

Should I take Glass Cannon in DRG Rogue Core? Only if your Enhancement deck has defensive layers that aren't health-dependent. Guardian with stun control, Retcon with Time Rewind charges, or Falconer in a squad with remote revive available. Without those layers, Glass Cannon at 10% max health ends runs on the first unavoidable hit.

Which upgrades are best for Guardian in DRG Rogue Core? Seismic Gloves stun duration and munition count. Secondary: residual area damage Enhancements after the fear zone expires. Skip raw damage multipliers that don't interact with the signature ability.

Which upgrades are best for Slicer in DRG Rogue Core? Kill-chain extension and chain trigger reduction. Blade damage multipliers compound with the chain bonus early. In co-op, chain duration Extension matters more than flat blade damage once teammates can contribute kills to chain maintenance.

What is meta-progression in DRG Rogue Core? Unlocks and minor bonuses that carry between runs. In the EA build it's limited to starting conditions. The Enhancement deck resets fully after every run. Meta-progression will expand significantly before 1.0.

How does pick order work in 4-player co-op upgrades? Each player gets 6 options selected in random order from a shared pool. Earlier pickers have wider choices; later pickers get what's left. Health Reward always appears in the final slot and is available to all four players. Plan high-priority picks for players who frequently pick first, not last.
