Wisdom Well 2.9.1: Costs, Probabilities, and What Actually Changed

Patch 2.9.1 quietly reworked the Wisdom Well.

No new Legendary skills were added. Yet the way Legendary skills are obtained, upgraded, and planned over time has fundamentally changed. Direct skill rolls are gone. Wisdom Elixir takes their place. Pity remains, probabilities shift slightly, and Corrosive Power becomes directly targetable for the first time.

This article breaks down how the new Wisdom Well actually works, what the numbers say about cost efficiency, how many Wishes you should realistically expect to spend, and whether this rework meaningfully improves Legendary skill progression or simply makes it easier to understand.

1. What Changed in Wisdom Well 2.9.1

The Wisdom Well in Patch 2.9.1 keeps its familiar shell but changes how progress is delivered.

The event still runs on Wishes.

Players still spend Divine Coins.

A pity system still exists.

What changed is what you are actually rolling for.

Before the rework, Wisdom Well was built around direct Legendary skill jackpots. When a selected skill hit, you received a fixed bundle of stones. That system worked, but it created friction. Over-upgrading, wasted stones, and awkward upgrade breakpoints were common, especially at higher levels.

Patch 2.9.1 replaces that structure with a currency-based model.

Legendary skill progress now flows through Wisdom Elixir, a universal currency obtained from Wishes and spent in the Wish Shop. Instead of hoping to land the right skill at the right moment, players accumulate Elixir and convert it into exactly the stones they need.

Several structural adjustments accompany this shift.

The ban function has been removed.

Exclusive Artifact fragments no longer appear in the reward pool.

Cinders of Wish are now obtained directly from Wishes.

Corrosive Power is no longer locked behind indirect progression.

The event cadence remains unchanged. Wisdom Well still runs multiple days per week, and bundle pricing is largely the same. What has changed is how randomness translates into long-term progress.

Legendary skills still require the same total investment to fully develop, but the path is now flatter, more modular, and easier to plan around.

Maël’s Opinion: This rework doesn’t make Legendary skills cheaper. The biggest change is not the cost, but the removal of wasted progress. Whether that feels better will depend on how much value you place on control versus jackpots.

2. Wisdom Elixir: The New Core Currency

Wisdom Elixir is now the backbone of the Wisdom Well. Every ability stones of Legendary skill progression routes through it.

Instead of rolling for a specific skill and hoping the timing lines up, you roll for Elixir and decide later how to spend it. That shift alone changes how the entire system behaves.

Here is how Elixir enters the system.

A 20 Elixir drop can occur on a high-value roll.

A 5 Elixir drop can occur independently.

The existing pity system remains, guaranteeing a 20 Elixir drop if you go too long without one (40 pulls).

Importantly, smaller Elixir drops do not reset pity. That detail matters. It means progress accumulates even during “bad” streaks instead of stalling.

Once earned, Elixir is spent in the Wish Shop. Each Legendary skill stone costs 5 Elixir. Unlocking a Legendary skill requires 60stones. Fully upgrading a Legendary skill to level 8 requires 240 stones (5 → 10 → 15 → 20 → 30 → 40 → 60 stones per level.)

This is the real improvement. Not generosity, but accuracy.

Under the old system, players routinely received stones they could not immediately use, especially at odd upgrade thresholds. Elixir removes that friction entirely. You buy exactly what you need, when you need it.

Corrosive Power is now available directly in the Elixir shop at the same cost as other Legendary skills. There is no longer a requirement to route through selection chests.

Maël’s Opinion: Wisdom Elixir doesn’t lower the ceiling, but it removes the noise. Legendary progression is now linear, predictable, and easier to budget for. If you care about planning rather than gambling, this is the single most important change in 2.9.1.

3. Wisdom Elixir, Probabilities, and What the Math Actually Says

The real change in the revamped Wisdom Well is mathematical.

The Elixir Drop Structure

Each wish now interacts with three relevant outcomes:

• A 20 Elixir drop at a low base probability, protected by a 40-wish pity
• A 5 Elixir drop at a smaller probability because that does not reset pity
• Everything else, which contributes no Elixir directly

The important point is this:

Elixir income is layered.

Pity guarantees progress. Small hits smooth variance. RNG still exists, but it no longer defines success or failure on its own.

This is already a structural improvement over the old jackpot model, where progress came in rigid blocks that often overshot actual upgrade needs.

Expected Value per Wish

When probabilities are flattened into expected value, each pull produces a small but measurable amount of Elixir on average. Not exciting on a single roll, but very relevant over hundreds.

This is where the system becomes predictable.

You are no longer asking: “Did I get the skill?” You are asking: “How many wishes until I reach the next breakpoint?”

Cost Anchors That Actually Matter

There are two numbers players should care about:

300 Elixir → unlocks one Legendary skill

1,200 Elixir → fully upgrades one Legendary skill to level 8

Once you think in Elixir breakpoints, the Wisdom Well stops feeling random and starts behaving like a long-form conversion system.

Variance Still Exists But It’s Contained

Luck still affects when you reach those thresholds.

It does not meaningfully affect whether you reach them.

The pity system caps bad streaks.

The 5-Elixir hits quietly accelerate good ones.

Over large samples, outcomes cluster closer than before.

This is where live data becomes important.

In the next section, I’ll plug in real pull statistics from a player who ran more than two thousand wishes under the new system. That’s where theory meets reality, and where we see whether the math holds under pressure.

Maël’s Opinion: This version of Wisdom Well finally behaves like a system instead of a slot machine. The cost is still high. The pace is still slow. But the rules are readable. That alone changes how players should approach Legendary skills going forward.

4. Real Pull Data — 2,420 Wishes, No Theorycrafting

Now let’s ground section 3 in reality. The data below comes from Shankarija (Server 417), who ran 2,420 wishes on the revamped Wisdom Well. Thank you for providing the stats. No theory, just what actually dropped.

Raw Results

• Total wishes: 2420
• Wisdom Elixir gained: ~2200
• Cinders of Wish gained: ~7000

That puts the averages at roughly:

• 0.9 Elixir per wish
• ~2.9 Cinders per wish

These numbers line up closely with the expected-value model outlined earlier. The important takeaway is not the exact ratio. It’s the consistency. What the Data Confirms :

• First, pity is doing its job. There are no catastrophic dry streaks. Progress never stalls for long. The 40-wish guarantee keeps Elixir flowing at a predictable pace.
• 5-Elixir hits matter at scale. They don’t feel impactful on individual pulls, but over 2,400 wishes they account for a meaningful share of total Elixir. They smooth the curve between jackpots exactly as intended.
• Third, variance affects timing, not outcome.

Shankarija didn’t get “lucky” in a way that breaks the model. Elixir totals sit right where the math says they should. Another player with similar volume would land close to the same place.

Converting This Into Progress

Using the breakpoints from section 3:

• 300 Elixir unlocks one Legendary skill
• 1,200 Elixir fully upgrades one Legendary skill to level 8

With ~2,200 Elixir:

• One Legendary skill can be fully maxed
• A second skill can be unlocked and partially upgraded up to level 7

And that’s without relying on extreme luck.

Cinders follow the same pattern. Around 7,000 Cinders over this sample confirms that Epic skill and artifact progression is noticeably faster than before, even if still RNG-driven.

This is the clearest signal so far that the revamped Wisdom Well behaves like a conversion system, not a lottery. You are not rolling to “hit” a skill. You are accumulating toward fixed thresholds.

Maël’s Opinion: This dataset confirms what the math suggested. The new Wisdom Well does not feel exciting on a single pull, but over thousands of wishes it becomes reliable. Costs are still high, and commitment is still required, but results are no longer at the mercy of extreme variance. If you engage seriously with the system, progress is no longer optional — it’s inevitable.

5. Corrosive Power and Targeted Progression

Corrosive Power is one of the clearest examples of what the Wisdom Well rework actually changes in practice.

Before patch 2.9.1, accessing Corrosive Power was indirect. Players had to rely on selection chests, It was part of a sequence rather than a deliberate choice.

With the rework, Corrosive Power now sits in the same category as Legendary skill. It uses the same currency, follows the same pricing per stone, and obeys the same rules. There is no special gating and no prerequisite progression path.

This has two immediate consequences.

First, targeting replaces sequencing. If Corrosive Power is the skill your account needs, you can pursue it directly. There is no need to wait for indirect unlocks via selection chest as previous version.

Second, cost visibility improves decision-making. Corrosive Power is not cheaper than before, but it is predictable. Players know the Elixir breakpoints, understand the total cost, and can estimate how many wishes are required over time. That clarity changes how the skill is approached. It is a quiet change, but a meaningful one.

Maël’s Take: Corrosive Power becomes a conscious choice rather than a milestone unlocked by coincidence. The cost remains high, but the path is finally clear.

Cinders of Wish: Faster, But RNG

Cinders of Wish were not replaced, but their flow changed.

Before patch 2.9.1, Cinders accumulated in a fixed way. Every wish contributed to the same amount (1), which made progression slow but stable.

With the rework, Cinders are now tied to wish outcomes (5% chance). Some pulls grant a Cinder reward, others do not. Over a large number of wishes, the average income is higher than before, but progress is no longer perfectly linear.

Players who engage heavily with the Wisdom Well will reach Cinder thresholds faster than in previous versions. However, short sessions may feel inconsistent, as progress depends on RNG rather than guaranteed accumulation.

The use of Cinders has not changed. They are still exchanged for Cinder skills, Alchemy Stones, and specific shop items. Only the speed at which they are earned has shifted.

Maël’s Take: Cinder progression is quicker overall. It rewards volume, not timing.

Maël’s Take: Better Structure, Same Commitment

The Wisdom Well rework succeeds at one thing: structure.

Progress is no longer hidden behind jackpots or inefficient overflow. Elixir turns Legendary skills into a long-form conversion problem instead of a slot-machine outcome. Costs are readable. Breakpoints are visible. Planning finally makes sense.

What it does not do is lower the bar.

Legendary skills are still expensive. Fully upgrading one still requires patience, volume, and a long-term mindset. The rework respects player investment better, but it does not shorten the road.

For players who engage with the Wisdom Well occasionally, little changes. For players who plan months ahead, the difference is substantial. You now know what you are committing to before you start, not halfway through.

This is not a generosity patch.

It is a transparency patch.

And in a system as central as Legendary skills, transparency is already a meaningful upgrade.
