- Depth Incremental upgrades split into progression, resource, and combat categories — match them to your current bottleneck.
- Best early buys: upgrades that increase depth progress and steps per run.
- Mid-game priority: resource efficiency upgrades that fund increasingly expensive tiers.
- Before Boss fights: invest in character strength, not farming speed.
- Rebirth synergy: permanent rebirth bonuses make every upgrade tier cheaper to reach.
How the Upgrade System Works
Depth Incremental, the Roblox incremental simulator by Core Loop, runs on a simple loop: buy Steps, dive, collect resources, upgrade, and repeat. Upgrades are where the loop compounds — every purchase either pushes you deeper, earns more per dive, or unlocks the ability to defeat the Boss gating the next zone.
The single most common mistake is spreading resources across low-impact options instead of targeting the current bottleneck. If your runs stall before reaching new areas, depth upgrades win. If you can reach the area but can't afford the next upgrade, resource upgrades win. If a Boss blocks the gate, combat upgrades win.
| Upgrade Category | Primary Effect | Best Stage | Value Rating |
|---|---|---|---|
| Depth and Progression | Pushes runs to greater depth | Early to Mid | ★★★★★ |
| Resource Efficiency | Increases income per dive | Mid | ★★★★☆ |
| Character Strength | Improves Boss performance | Boss gates | ★★★★☆ |
| Steps Purchases | Boosts starting progress per run | All stages | ★★★★☆ |
| Situational Growth | Fills build-specific gaps | Late | ★★★☆☆ |
Before every purchase, ask one question: what is stopping my next run from going deeper? Buy the upgrade that answers that question, nothing else.
Upgrade Tier List
This tier list ranks upgrade directions by general value across the game's three progression stages. Tiers are context-dependent — a B-tier option for one player can be A-tier for another if it targets their exact bottleneck.
| Tier | Upgrade Direction | Priority | Best For | Key Weakness |
|---|---|---|---|---|
| S | Depth and Progression | Highest | Unlocking deeper areas, breaking run limits | Doesn't fix resource shortages |
| A | Resource Efficiency | High | Funding expensive mid-game upgrades | Low value when depth is the only limit |
| A | Character Strength | High | Boss challenges, surviving deep runs | Inefficient when farming is the bottleneck |
| B | Situational Growth | Medium | Fine-tuning an established build | Highly stage-dependent |
S: Depth Upgrades
- Directly serves the main goal
- Value across exploration and farming
- Buy whenever runs stall
A: Resource Upgrades
- Shortens upgrade cycles
- Scales with rising costs
- Core mid-game investment
A: Strength Upgrades
- Breaks Boss gates
- Converts resources into combat progress
- Match to Boss requirements
B: Situational Picks
- Fills specific gaps
- Best after core tiers are covered
- Read the effect before buying
Spreading purchases across many low-impact upgrades is the most common reason mid-game progress slows before a Boss. Concentrate resources on one bottleneck at a time.
Step-by-Step Upgrade Route
Follow this route to convert every dive into the highest-value purchase available. The order matters: stability first, efficiency second, combat readiness third.
Establish the Core Loop
Buy Steps before each dive, collect everything the run generates, and reinvest immediately. In the earliest stage, prioritize upgrades that increase the progress gained per run so the loop compounds faster.
Push Depth Over Comfort
Farm the deepest area you can clear consistently. Skip Boss attempts until the basic upgrade loop is established — an early failed Boss attempt wastes a run without permanent gain.
Shift to Resource Efficiency
Once depth access is stable, redirect income into upgrades that make repeated runs more profitable. This funds the rapidly rising costs of the next progression tier.
Prepare the Boss Check
When a Boss gates your next area, compare your build against the encounter's requirements. Invest in the attributes your build actually uses, then use one attempt as a progress check rather than repeatedly retrying.
Rebirth and Repeat
When a rebirth reward would noticeably accelerate the next cycle, reset. Permanent rebirth bonuses lower the effective cost of every upgrade tier you just climbed, making the second pass faster.
Advance to the next depth only when your resource income consistently funds the upgrades that area requires. Pushing early turns runs into low-return farming.
Stage-by-Stage Priorities
| Stage | Depth Focus | Top Upgrade Goal | Advance When |
|---|---|---|---|
| Early | Currently accessible depth | More progress per run | Next upgrade is fundable without idle farming |
| Mid | Deeper unlocked areas | Balance depth access and income | Boss requirement is reliably approachable |
| Late | Deepest available areas | Sustained long-dive performance | Boss is beaten consistently, next depth outperforms old farm |
After a failed Boss attempt, don't re-purchase blindly. Reassess the full upgrade path, prioritize the weakest core attribute, and consider a rebirth cycle to make the retry faster.
Upgrade Milestones to Hit:
- Core loop established: Steps bought before every dive
- Deepest efficient farming area identified
- Resource income funds next progression tier
- Boss requirements matched to build attributes
- Rebirth timing evaluated each cycle
Rebirth and Upgrade Synergy
Rebirth resets temporary run progress but keeps permanent rewards, which changes upgrade math. After a reset, upgrades you already understand become cheaper relative to your boosted baseline, so the same tier list applies — you simply climb it faster each cycle.
Compare the value of the next reset against nearby temporary gains: if a milestone is minutes away and unlocks a meaningful permanent advantage, push first; otherwise, reset now and let the rebirth bonus compound your next upgrade route.
FAQ
Q: What are the best Depth Incremental upgrades to buy first?
Early on, prioritize upgrades that increase the progress gained per run, such as additional Steps and depth progression upgrades. These compound the core loop fastest and make every later purchase easier to afford.
Q: Should I upgrade resource efficiency or depth progression first?
Buy depth progression when your runs stall before reaching new areas, and resource efficiency when you can reach an area but can't afford the next upgrade. Match the purchase to your current bottleneck rather than following a fixed order.
Q: When should I stop upgrading and fight the Boss?
Attempt the Boss once your upgrades provide a consistent advantage rather than hoping for one lucky run. Use the first attempt as a progress check — if it fails, return to farming and strengthen the weakest attribute your build relies on.
Q: How does rebirth change my upgrade strategy?
Rebirth resets temporary progress but keeps permanent rewards, effectively lowering the cost of re-climbing the same upgrade tiers. Reassess your priorities after each reset, because boosted baselines can shift which upgrade is now the best value.
