PoE2 Chaos Orb Reroll vs Restart: 31 div vs 580 div

Chaos Orbchaos spamrestartexpected costgloves

When a target mod gets wiped mid-craft in PoE2, rerolling it with Chaos Orbs is far cheaper than starting over. On one pair of gloves, putting "+2 to Level of all Projectile Skills" back with Chaos Orbs averaged about 31 div (div = Divine Orb), while restarting from a white base cost about 580 div. And each Chaos Orb lands it only 0.32% of the time (measured on the engine).

My Orb of Annulment took my best mod with it. I'm throwing this away and starting over...

Metan

Wait. If you work out the expected cost to finish, restarting is the losing move.

Zundamon

Zundamon

Chaos lands it only 0.32% of the time, and rerolling is still cheaper!?

Rerolling Costs About 31 div, Restarting About 580

First, let's compare the two options when +2 Projectile is lost.

Zundamon

Zundamon

What kind of gloves are we crafting?

Metan

Metan

A pair of Intelligence gloves. They start as a Rare with one Fractured prefix and "+2 to Level of all Projectile Skills" on the suffix side.

Metan

Metan

There's one more prefix on it too. We add the remaining targets from there.

Zundamon

Zundamon

What are the remaining targets?

Metan

Metan

Maximum Energy Shield or maximum Mana at T1, the mods from the Essence of Hysteria and the Essence of Horror, and Astrid's Creativity.

Zundamon

Zundamon

But the +2 Projectile can get wiped, right?

Metan

Metan

Removing misses with a plain Orb of Annulment sometimes hits it. When that happens, you have two options.

When it's lostCostDetailsWhy that much
Reroll it with Chaos Orbsabout 31 div on averagelands 0.32% per orb (engine)low hit rate, but you only spam Chaos Orbs
Restart from a white baseabout 580 divcalculated: about 190 div per magic-to-Fractured attempt × 3, plus Astrid's Creativityyou walk the whole long road again

By calculation, rerolling is an order of magnitude cheaper.

Zundamon

Zundamon

Even at 0.32%, it's an order of magnitude cheaper than restarting!

Metan

Metan

Because restarting means redoing everything: lining up targets on a magic item, making it Rare, then fracturing.

Zundamon

Zundamon

But with bad luck, the Chaos Orbs could go on forever?

Metan

Metan

In the engine runs, the longest streak was 2,500 orbs.

Metan

Metan

The calculation treats rerolling as spam and stops it at a 3,000-orb cap.

What Does a "Restart When Lost" Rule Cost?

The same choice comes back every time the mod is lost, so we compared the expected cost to finish for the whole route.

Zundamon

Zundamon

Doesn't comparing one reroll with one restart already settle it?

Metan

Metan

Not yet. The choice keeps coming back, so we have to compare whole routes.

Rule when +2 Projectile is lostCalculatedEngineWhich wins
Reroll with Chaos Orbs (cheapest route)105 div94 div (1,000 runs)wins
Restart (cheapest route under that rule)775 div788 divloses (smart play elsewhere doesn't bring it down)

Under the restart rule, the cost never got below 775 div by calculation.

Zundamon

Zundamon

Do the calculation and the engine agree?

Metan

Metan

Both rows land close. 94 div against 105, and 788 div against 775.

Zundamon

Zundamon

What does the cheapest route actually do?

Metan

Metan

It clears misses with plain Annulments and almost never uses Omens. The details are in PoE2 crafting expected cost.

Metan

Metan

Here we only look at one question: keep going, or start over?

In Another Example, Was Restarting Ever Right?

From here on is a different example. Same glove setup, but with different suffixes on the finished item.

Zundamon

Zundamon

A different example? What changed?

Metan

Metan

The finished suffixes are +2 Projectile, Critical Damage Bonus and attack speed.

Metan

Metan

We split it into 54 situations by targets present, prefix misses and suffix misses.

Zundamon

Zundamon

How much does a restart cost in this one?

Metan

Metan

69 div, to rebuild the first half up to the Fractured item. Much cheaper than the first gloves.

Zundamon

Zundamon

Then restarting has to win somewhere!

Metan

Metan

It won zero times. It was always at least 67 div worse than the best move.

Targets presentPrefix missesSuffix missesRestart loss (T1 targets)Restart loss (T3+ targets)What you throw away
001+69 div+69 divthe restart price only
101+85 div+73 divrestart price + 1 target's value
210+1,601 div+361 divrestart price + 2 targets' value
310+5,037 div+2,281 divrestart price + 3 targets' value
410+5,129 div+2,429 divrestart price + 4 targets' value

The more targets you hold, the bigger the loss, by orders of magnitude.

Zundamon

Zundamon

With no targets on the item, restarting can't hurt, right?

Metan

Metan

It still costs its price, 69 div. You'd land in almost the same "no targets yet" state you're already in.

Zundamon

Zundamon

And with three or four targets on it?

Metan

Metan

If they're all T1, you throw away over 5,000 div. You lose the value of every target you're holding.

The 580 div Was Too High. Does the Answer Hold?

The first gloves' restart cost of about 580 div came from our first calculation, and it later turned out too high.

Zundamon

Zundamon

The 580 div was wrong!?

Metan

Metan

Orbs of Transmutation and Augmentation used on magic items have their own tier floors, separate from Exalted Orbs: Greater 44, Perfect 70.

Metan

Metan

The first calculation used the Exalted Orb floors, 35 and 50. That doubled the estimated magic-stage cost.

Transmutation / Augmentation floorGreaterPerfectWhat happened
Correct value4470not used in the first calculation
Value used first (same as Exalted Orb)3550magic stage estimated at 2 times, so the 580 div is too high

The 580 div is too high by the magic-stage overestimate.

Zundamon

Zundamon

So the answer might change too?

Metan

Metan

We expect it to point the same way. But that's an inference.

Metan

Metan

Two reasons. In the other example, even a 69 div restart was never chosen, and the gap to the 31 div reroll is large.

Metan

Metan

We haven't checked it on the first gloves.

Zundamon

Zundamon

Did you notice anything else?

Metan

Metan

+2 Projectile is also cheap to add with Chaos Orbs after making the item Rare. Cheaper than Augmentation spam on the magic item, which is 178 div per attempt by calculation.

Metan

Metan

So the very first step of the route could be rethought. But the 178 div carries the same floor mistake.

  • The about 580 div restart cost is calculation only and too high by the floor mistake above. It hasn't been recalculated with corrected floors or checked on the engine.
  • The 54 situations and "always at least 67 div worse" come from a different example and are comparisons inside the calculation (a calculation experiment, not a site feature). Applying them to the first gloves is an inference, and they weren't checked against in-game results.
  • 0.32% comes from the ExileDesk engine and wasn't compared with Craft of Exile or in-game results. The price of buying the base isn't included.

When a target mod is lost, rerolling from what you have is cheaper than restarting, by calculation. Before you scrap an item, count the targets still on it.

Where the Numbers Come From

Show sources (5)
  • First gloves, engine values (analysis log optimal-craft-dp, 2026-10-21): 0.32% per Chaos Orb, longest reroll streak of 2,500, reroll route 94 div (1,000 runs), restart rule 788 div (run count not recorded).
  • First gloves, calculated values (same log): reroll about 31 div on average, restart about 580 div (about 190 div × 3 + Astrid's Creativity), 105 div and 775 div, 3,000-orb reroll cap.
  • The 580 div overestimate (later notes in the same log, calculation): Transmutation / Augmentation floors Greater 44, Perfect 70, and 178 div per magic attempt.
  • Different example (docs/org/math/notes/threshold-2026-10-20.md): the 54-situation table, the 69 div restart and "at least 67 div worse" are all calculation.
  • Prices are market prices from 2026-10-21 (1 div = 718 Exalted Orbs).
