PoE2 Cast Speed Weight: 1 on poe2db, 1,000 in CoE
PoE2 ring Cast Speed has a modifier weight of 1 on poe2db (all five tiers, a placeholder) but 1,000 in Craft of Exile and ExileDesk. At 1,000, Omen of Dextral Exaltation + Greater Exalted Orb lands Cast Speed T2 or better 4.37% of the time. Use poe2db's 1 as-is and it drops to 0.00%, so any Cast Speed ring looks absurdly expensive.
Zundamon
I opened poe2db's ring page, and Cast Speed has a weight of 1.
Metan
Other mods sit around 1,000. If that were true, it would roll a thousand times less often.
Zundamon
That can't be right. Which number is correct?
Metan
Let's line up poe2db, Craft of Exile and the ExileDesk engine and check.
What a Weight Is
When a mod is added, the weights of all eligible mods are summed, and one is picked in proportion to its weight.
Zundamon
So how does a weight actually work?
Metan
With twenty mods at weight 1,000, each one has a one-in-twenty chance.
Zundamon
And if a weight-1 mod is mixed in?
Metan
That mod is almost never picked.
Zundamon
Can't we just read the weights from the game data?
Metan
The game data (the client) doesn't contain PoE2 weights. So every tool takes them from outside sources.
Three Sources Side by Side
Gold Ring suffix weights for Cast Speed, Rarity and all Elemental Resistances (the same value on every tier).
| Source | Cast Speed (5 tiers) | Rarity (suffix, 3 tiers) | all Elemental Resistances (5 tiers) | What it looks like |
|---|---|---|---|---|
| poe2db ring page (checked 2026-10-22) | 1 | 1,000 | 800 | Only Cast Speed is far smaller |
| Craft of Exile (local copy, 2026-10-09) | 1,000 | 1,000 | 800 | All three are normal weights |
| ExileDesk engine | 1,000 | 1,000 | 800 | Same as Craft of Exile |
The only difference is poe2db's Cast Speed.
Zundamon
Only poe2db has Cast Speed at 1!
Metan
All five tiers are 1. In the page data, the other rows hold text values like "1000", but these five hold the number 1.
Zundamon
Why would it be like that?
Metan
It looks like a placeholder 1 for a mod new in PoE2 whose weight isn't known.
Zundamon
How does Craft of Exile have it?
Metan
Ring Cast Speed is 1,000 per tier. On amulets it's 800 per tier.
Zundamon
And what does ExileDesk do?
Metan
We haven't used poe2db's 1 since 2026-09-23. Any mod at 1 or less on every tier is treated as a placeholder and filled from Craft of Exile.
Metan
So the current value is 1,000, the same as Craft of Exile.
How Much the Weight Changes the Odds
On a Gold Ring with Fractured Spell Damage and Rarity T1, we used Omen of Dextral Exaltation + Greater Exalted Orb. Only the Cast Speed weight was changed, and the engine counted the rates over 20,000 runs each.
| Cast Speed weight | Rolls T2 or better | Rolls any tier | What happens |
|---|---|---|---|
| 1,000 (Craft of Exile, ExileDesk) | 4.37% | 6.52% | Rolls now and then |
| 1 (poe2db) | 0.00% | 0.01% | Almost never rolls |
At weight 1, Cast Speed almost never rolls.
Zundamon
4.37% turns into 0.00%!
Metan
If you use poe2db's 1 as-is, an Exalted Orb will almost never give Cast Speed.
Zundamon
What if a cost tool used that value?
Metan
Any Cast Speed ring would look absurdly expensive.
Metan
All our Gold Ring cost posts, like Don't Hoard Your Misses, use weight 1,000.
We Once Lowered It to 60, Then Went Back
ExileDesk itself once lowered the Cast Speed weight to 60.
Zundamon
ExileDesk got it wrong too!?
Metan
We worked the weight back from how many Chaos Orbs it took to hit.
Metan
But that count was until Cast Speed T1 rolled, not any tier.
Zundamon
So how often does T1 roll?
Metan
In Craft of Exile's simulator, we used Chaos Orbs on a ring with one fixed mod and one miss.
| What we counted | Number | What it showed |
|---|---|---|
| Average until T1 | Once every 152 | Weight 1,000 explains it |
| Hits counted | 55 | — |
| Worst case | 566 | Bad luck can take several times the average |
Counted as T1 only, weight 1,000 explains the numbers. So we went back to Craft of Exile's value.
Zundamon
Mix up the tier, and you read the weight several times too small.
Metan
Right. When you look at a count, first check whether it's about T1 or any tier.

poe2db's ring Cast Speed weight of 1 looks like a placeholder, and ExileDesk uses 1,000, the same as Craft of Exile. When you read a weight, always check its source and its tier first.
