PoE2 Crafting Simulator Custom Weights: Edit Mod Weights
ExileDesk, a PoE2 crafting simulator, has a feature that lets you change mod weights yourself on the crafting bench (not released yet; no release date). On a Gold Ring with an Orb of Augmentation, lowering Cast Speed from the default weight of 1,000 to 200 drops its chance from 5.4% to 1.1%.
Zundamon
So what's the right weight for Cast Speed on rings?
Metan
Honestly, nobody knows. poe2db lists 1 on all five tiers, while Craft of Exile and ExileDesk use 1,000.
Zundamon
They don't even agree! Then which one should I trust?
Metan
That's why we built it with a default you can edit. The owner put it simply: "Put it at 1000, and make it editable."
Why Make Weights Editable?
The game data doesn't include PoE2 weights, so every tool borrows them from outside sources. That's why the numbers differ from source to source.
Zundamon
What does a weight actually do?
Metan
When a mod is added, the weights of all eligible mods are summed. Then one is picked in proportion to its weight.
Metan
So a weight five times larger makes that mod roughly five times more likely.
Zundamon
Cast Speed was split between 1 and 1,000. Which one does ExileDesk use?
Metan
Since 2026-09-23, we treat poe2db's 1 as a placeholder and use Craft of Exile's 1,000.
Metan
The details are in PoE2 Cast Speed Weight: 1 on poe2db, 1,000 in CoE.
Zundamon
So 1,000 is the right answer!
Metan
That's not guaranteed either. So we only pick the default, and you get the final say.
How Much Does the Weight Change the Odds?
Here is how often Cast Speed is added when you use an Orb of Augmentation on a Magic Gold Ring with one prefix. Only the Cast Speed weight changes.
Zundamon
How big a difference does the weight make?
Metan
Let's line up the odds table, the mod list, and 4,000 real rolls for each weight.
| Cast Speed weight | Odds table | Mod list | 4,000 rolls | What it looks like |
|---|---|---|---|---|
| 1 (poe2db's value) | 0.01% | 0.01% | 0.03% | Almost never |
| 200 | 1.14% | 1.14% | 1.13% | Rare |
| 1,000 (default) | 5.43% | 5.43% | 5.03% | ExileDesk today |
| 5,000 | 22.30% | 22.30% | 21.80% | More than 1 in 5 |
The odds table and the mod list agree, and the 4,000 rolls land close to them.
Zundamon
At weight 1 it almost never shows up, but at 5,000 it's more than one in five!
Metan
The same ring looks completely different depending on which weight you believe.
The Result: One Change, Applied Everywhere
The main design goal was no mismatched numbers.
Zundamon
Which tier's weight do you edit?
Metan
The weight of the mod's heaviest tier. The other tiers scale by the same ratio.
Metan
All five Cast Speed tiers share one weight, so all five take the value you enter.
Zundamon
Could the rolls and the odds table end up with different numbers?
Metan
The weight is applied in exactly one place, where candidate mods are drawn. Rolls and the odds table both go through it, so both change the same way.
Metan
The mod list's tier table uses the edited weight too. That single path is why the odds table and mod list match in the table above.
Zundamon
Does my edit disappear when I close the page?
Metan
No, your browser remembers it.
What Does It Look Like on Screen?
Open a row in the mod list and a bar appears above its tier table: "Weight [1000] Default 1000 ↺ Reset all (n)". (We checked this on the unreleased screen.)
Zundamon
What happens if I type 200 there?
Metan
Cast Speed drops from 5.4% to 1.1%, and each tier in the tier table shows 0.2%.
Metan
The row label changes too. Rows with estimated weights keep the existing "Est. weight" label, and rows you edited show "Weight edited".
Zundamon
How do I put it back?
Metan
Press "Reset all". You get 5.4% and "Est. weight" back, and the saved values are cleared from your browser.
Metan
One catch: grouped rows (several mods bundled into one row) don't get this bar.
Are Edited Weights Kept in Replays and Shares?
Yes. Edited weights are written into every step of the craft, and they replay and share the same way Omen settings do.
Zundamon
What about steps that don't have a weight written in?
Metan
They roll with the default weights.
Zundamon
Does a replay really use the weights in the craft?
Metan
We recorded an Orb of Alchemy plus six Chaos Orbs at weight 5,000, then replayed it with the on-screen weight left at 1.
Metan
The replay matched the recording. It still matched after a share round trip, and it differed from a craft at the default weight.
Zundamon
So it uses the weights written in the craft, not the ones on screen!
Metan
Right. When you share a craft, "this assumes weight 5,000" travels with it.

- The numbers above come from ExileDesk's own consistency script (comparing values inside the engine) and from the screen. They have not been compared with in-game results or Craft of Exile.
- The default of 1,000 for Cast Speed is borrowed from Craft of Exile; whether it is the game's real weight is unknown.
- This feature is not released yet and is not on the live crafting bench. No release date is set.
Zundamon
What should I do if I can't decide which weight to trust?
Metan
Check the odds once at each candidate weight. That shows how much the mod actually drives your cost.
Weights nobody can confirm get a default that you can edit (coming later). An edited weight applies the same way to rolls, the odds table and replays.
Where the Numbers Come From
Show sources (3)
- Augmentation odds (odds table, mod list, 4,000 rolls): ExileDesk engine, a consistency script run on 2026-10-22 (emulator team note 2026-10-22-mod-weight-edit). Label: engine (not external truth).
- 5.4% to 1.1% on screen, 0.2% per tier, and the label texts: checked on ExileDesk's internal build at 1660×860 (same note). Label: engine.
- Weight sources (poe2db 1, Craft of Exile 1,000, ExileDesk 1,000 since 2026-09-23): the table in our earlier post. Label: poe2db / CoE. The game's real weight is an estimate (nobody knows it).
Try It Yourself
Open a Gold Ring on the live crafting bench and look at the chance column in the mod list. It shows the odds at weight 1,000 today. Weight editing is not released yet (no release date); we'll update this post when it goes live.
