In Path of Exile, profit strategies often come and go with each league, but few mechanics spark as much experimentation as gem imbuing with the new "coins." This system-powered by Coins of Power, Skill, and Knowledge-lets players add level 1 support gems to skill gems, creating randomized outcomes with wildly different profit potential.

 

After testing nearly 700 gems across multiple imbuing runs, a clear conclusion emerges: this system can still be highly profitable, but only if you understand probabilities, gem selection, make POE currency and market behavior.

 

Understanding the Impure Gem System

 

The core mechanic revolves around three league-specific currencies:

 

 Coin of Power

 Coin of Skill

 Coin of Knowledge

 

Each coin type adds a random support gem to a selected skill gem. The catch is that outcomes are not equal. Some skill gems can roll over 100 possible supports, while others have fewer than 10.

 

This creates a massive variance in hit rates:

 

 Low-risk setups: ~100% chance for desirable outcomes

 High-risk setups: below 3% chance for specific valuable supports

 

The goal is simple: identify gems where the probability of hitting valuable outcomes outweighs the cost of the coin.

 

Why Data Tools Matter (But Aren't Perfect)

 

To estimate value, external tools are used to approximate possible outcomes per gem. These tools help identify:

 

 Number of possible supports per skill gem

 Likely high-value outcomes

 Risk-to-reward ratios

 

However, they are not fully accurate. Some gem listings are outdated or mislabeled, and market prices fluctuate too quickly for precise prediction.

 

Because of this, real profitability depends less on theoretical math and more on practical market testing.

 

Market Analysis: How Gems Were Selected

 

The first step in optimizing profit is filtering skill gems based on their number of possible impure outcomes.

 

A key rule emerges:

 

 Gems with under 10 possible outcomes are ideal

 Gems with 40+ outcomes are high-risk gambling options

 

For example:

 

 Herald of Purity → too many outcomes → poor target

 Herald of Ash → fewer outcomes → better control and consistency

 

This immediately narrows the field to more predictable profit generators.

 

Using POE Ninja for Real Demand

 

Beyond theoretical odds, real demand determines profit. Using trade and build data sources, the most commonly used skill gems were identified.

 

This revealed a key insight:

 

Most profitable gems fall into one of two categories:

 

1.Frequently used skills with predictable outcomes

2.Low-supply niche gems with high-demand supports

 

A secondary method involves checking actual builds and seeing which supports players are actively using. In most cases, only one or two outcomes per gem carry meaningful value.

 

Best Coin Strategies

 

Coin of Power (Low Risk Core Strategy)

 

This is the most consistent and profitable category.

 

Best targets include:

 

 Life Tap supports

 Arrogance (auras)

 Moderation

 Cruelty

 Eternal Blessing

 Inspiration

 

These combinations often have:

 

 Low outcome pools

 Stable demand

 Predictable resale value

 

Coins of Power represent the safest entry point for consistent profit.

 

Coin of Skill (Moderate Risk)

 

This category is more volatile. The only consistently profitable subgroup identified:

 

 Mark Skills

 

Why?

 

 Mark on Hit setups often have only 3-4 possible outcomes

 Reasonable demand in meta builds

 Fast resale compared to other skill pools

 

Everything else tends to have 30-50+ outcomes, making them closer to gambling than strategy.

 

Coin of Knowledge (High Variance)

 

This category showed mixed results.

 

 Curse gems were the most stable options

 However, demand was weaker than expected

 Many outcomes simply do not sell quickly

 

In comparison, Coins of Power consistently outperform Knowledge coins in both stability and profit margin.

 

Profit Calculation Method

 

Each test used a simple expected value formula:

 

Expected Profit = (Chance of Valuable Outcome × Sale Value)-Coin Cost

 

Key considerations:

 

 Gem quality must be applied before imbuing (it is consumed during corruption process)

 

 Market prices shift rapidly

 

 Outliers heavily distort averages

 

Because of these factors, real profit can only be confirmed through bulk testing.

 

Real Testing Results (700 Gems Total)

 

Across multiple sessions, approximately 700 gems were imprinted using all three coin types.

 

Key results:

 

 ~1000 Divine Orbs total revenue generated

 Sub-600 Divine investment cost

 Approximate profit: +400 Divine net gain

 

However, this came with caveats:

 

 Some gems sold instantly

 Others took days to move

 A few required multiple price adjustments

 

Liquidity is a major factor in this strategy.Test Breakdown

 

Test 1: High-Value Power Gems

 

Focused on best theoretical margins.

 

Results:

 

 Strong initial sales

 Some slow-moving supports (e.g., Cruelty variants, Detonate Dead)

 High early profit before market adjustments

 

Test 2: Skill Coins (Mark Skills Focus)

 

Focused on mark-related outcomes.

 

Results:

 

 Faster sales

 Lower but stable margins

 One of the most reliable mid-risk options

 

Test 3: Knowledge Coins

 

Focused on curse and infuse outcomes.

 

Results:

 

 Weak demand

 Slower sales

 Lower profitability than expected

 

Conclusion: weaker than Power coins overall.

 

Test 4: Aura-Based Power Coins

 

Focused on Arrogance and support gems.

 

Results:

 

 Decent profit

 Slow turnover

 Stable but not explosive gains

 

Test 5: Repeat High-Performers

 

Focused again on best-known combinations.

 

Results:

 

 Strong alignment with expected profit model

 One of the most efficient cycles

 

Test 6: Mixed Utility Gems

 

Included curses and niche skills.

 

Results:

 

 Surprisingly strong sales in some cases

 Elemental Weakness underperformed

 Overall stable but inconsistent

 

Market Reality: Selling Is the Hard Part

 

One of the biggest challenges is not imbuing-it's selling.

 

Key issues:

 

 Gems move slowly in bulk

 Prices require constant adjustment

 Flooding the market reduces value

 Competition from other sellers impacts margins

 

Even highly profitable gems can sit unsold for days.

 

Key Lessons Learned

 

1.Coins of Power are the safest and most consistent profit source

2.Mark Skills are the best low-risk Coin of Skill targets

3.Coins of Knowledge are inconsistent and often inferior

4.Bulk listing reduces market value if overdone

5.Profit comes from volume + selection, not single hits

 

Final Thoughts: Is Gem Imbuing Still Worth It?

 

Yes-but with conditions.

 

This is not a passive income strategy. It requires:

 

 Constant market tracking

 More POE exalted orbs

 Smart gem selection

 Frequent price adjustments

 High-volume trading cycles

 

When optimized, the system can average around 1 Divine Orb per imbuing action, but real-world results vary depending on timing and demand.

 

Compared to alternatives like double corrupting, this method is:

 

 More time-consuming

 More inventory-heavy

 But still consistently profitable when managed correctly

 

For players willing to micromanage listings and study the market, gem imbuing remains a strong league mechanic for profit generation in Path of Exile.
