PoE2 Catalysing Exaltation Multiplier: No One Knows It
The poe2 Catalysing Exaltation multiplier has no official number from the game. ExileDesk defaults to Craft of Exile's formula, 1 + 0.2 × quality (5x weight at 20% quality), which doesn't contradict the two measurements posted on Reddit. The in-game value is still unconfirmed, so ExileDesk lets you set the multiplier yourself.
Zundamon
Build Catalyst Quality, then use an Exalted Orb with Omen of Catalysing Exaltation. That's the standard ring craft!
Metan
It's a way to pull your target mod with extra weight. So at 20% quality, how much more likely is it?
Zundamon
Easy, I'll just look it up!
Metan
Here's the thing: nobody knows the official number. poe2db's description gives none, and the theories going around all disagree.
Zundamon
Nobody knows?! Then what number does ExileDesk use?
Metan
I'll be honest about the number we use now, and how solid its basis really is.
The Default Is CoE's 1 + 0.2 × Quality
First, here is how the ExileDesk engine handles Omen of Catalysing Exaltation.
Zundamon
What happens inside the engine when I use an Exalted Orb with the omen?
Metan
It multiplies the weight of the mods matching the quality type. Then the quality is used up.
Zundamon
How does it decide which mods match?
Metan
On rings and amulets, it goes by mod tags.
Zundamon
And where does the multiplier come from?
Metan
It's the same formula Craft of Exile (CoE) uses. Here it is as a table.
| Quality | Multiplier | What happens |
|---|---|---|
| 0–20% | 1 + 0.2 × quality (5x at 20%) | More quality means more weight on matching mods |
| Above 20% | +0.12 per extra 1% | The growth slows down |
Metan
This formula went in with v0.1.525. On 2026-10-16 the owner decided to "match CoE."
Why Is There No Official Number?
Zundamon
Surely poe2db lists the multiplier?
Metan
The weights on poe2db and CoE are worked out from community measurements.
Metan
And poe2db's description only says it increases the chance. It never says by how much.
Zundamon
Are there any other clues?
Metan
On the official forum, some suspect it doesn't work when stacked with other omens. There's also a bug report that it does nothing on jewels.
Metan
There are a few theories about the multiplier, but none has clear backing.
Zundamon
So was CoE's formula read out of the game?
Metan
No, it wasn't. For now, it's honestly best seen as the most complete working estimate.
Only Two Data Points, From Reddit
The only outside measurements we found were two points posted on Reddit.
| Quality | Result | Compared with CoE's formula |
|---|---|---|
| 1.5% | 42 out of 100 | Inside the 95% interval (no contradiction) |
| 40% | 77 out of 100 | Inside the 95% interval (no contradiction) |
Zundamon
Both inside the interval? Then the formula is proven right!
Metan
We can't go that far. All we can say is that the formula doesn't contradict the measurements.
Zundamon
Why not?
Metan
Two points of 100 tries each leave a wide band. A different formula could fit inside it too.

- The real in-game multiplier is unconfirmed. The default 1 + 0.2 × quality is CoE's formula, not a number read from the game.
- The +0.12 per 1% above 20% quality also just keeps the shape of CoE's formula.
- The suspicion that it fails when stacked with other omens is not modeled in the engine.
- The odds table and 2,000-use results in the next section only check that the engine's table matches what the engine rolls. They were not compared with in-game results.
How Much Does the Multiplier Change Life Mods?
We put 20% Life quality on a Gold Ring and added one mod with an Exalted Orb and Omen of Catalysing Exaltation. Here is how often the engine gave a Life mod.
Zundamon
If the multiplier is only a little off, the result barely changes, right?
Metan
Actually, it changes a lot. Take a look.
| Setting (per 1% quality) | Odds table | 2,000 uses | What happens |
|---|---|---|---|
| No omen | 13.3% | — | Life keeps its normal weight |
| 0 | 13.3% | 13.2% | Same as no omen |
| 0.2 (default, 5x weight) | 43.4% | 43.4% | Far more likely than no omen |
| 0.5 (11x weight) | 62.8% | 63.8% | More than half |
| 1 | 76.3% | 78.0% | The most likely in the table |
Zundamon
43.4% at the default 0.2, and 62.8% at 0.5!
Metan
That one number moves your craft cost estimate a lot.
Zundamon
The odds table and the 2,000 uses are almost the same.
Metan
Yes. But that only checks the engine's table against the engine's own rolls. It wasn't compared with in-game results.
Bottom Line: You Set the Multiplier
Hard-coding one number when we don't know the right one wouldn't be honest. So since v0.1.589, you can change the setting under an omen's name once you apply it.
Zundamon
What can I set?
Metan
Two things. Here they are.
| Omen | What you can set | Default |
|---|---|---|
| Omen of Catalysing Exaltation | The multiplier per 1% quality | 0.2 (5x at 20% quality). At 0.5 the weight becomes 11x |
| Omen of Sanctification | Tick the checkbox to pick the multiplier yourself (0.78–1.22x) | Unticked |
Zundamon
What about quality above 20%?
Metan
It keeps the shape of CoE's formula. Only the slope changes.
Metan
Crafting and the odds table read the same formula. So when you change the setting, the odds update right away.
Zundamon
Which number should I enter?
Metan
If you have your own results or a measurement you trust, enter that.
Metan
I'm not confident in this number either. It's something I'd like to settle together with the people using the tool.
The Catalysing Exaltation multiplier has no official number, and the default is a working estimate from CoE's formula. Since you can change it yourself, the quickest path is to estimate with a range.
Where the Numbers Come From
Show sources (6)
- The formula 1 + 0.2 × quality, +0.12 per 1% above 20%: Craft of Exile's data (adopted in v0.1.525). poe2db / CoE (CoE's formula; unconfirmed in game)
- The "increases the chance" description: poe2db. poe2db / CoE
- 1.5% quality: 42 out of 100, 40%: 77 out of 100: Reddit measurements. In game (two points only; consistent with the formula within 95% intervals)
- The stacking suspicion and the jewel bug: official forum posts. Estimate (not verified)
- Life mod chances (13.3%, 43.4%, 62.8%, 76.3%) and the 2,000-use results: the ExileDesk engine's odds table and 2,000 engine uses. Engine
- The multiplier setting: v0.1.589 release notes
Try It Yourself
On the Gold Ring crafting bench, apply Omen of Catalysing Exaltation and change the multiplier under its name.
