How many openings for a perfect Turmacan’s Bracelet?

Opening a Sealed Turmacan’s Bracelet rolls its grade, slot, slot option, and three varying stats. Getting everything right has roughly a one in 41.3 million chance per opening. A useful bracelet is much more attainable if you accept lower varying stats.

What counts as perfect?

For this article, a perfect bracelet meets all three requirements:

• High grade. Low and Medium bracelets don’t count.
• One slot with either +50 Penetration or +140 PvE All Attack Up. Both options are accepted.
• Three varying stats, each either +13% Critical Damage or +6% All Skill Amp. Lower values and All Attack Up don’t count.

The bracelet always gets three varying stats. Each independently rolls its value tier, then its stat type; repeated stats are possible. Any mix of the two accepted maximum stats qualifies, regardless of order.

First, the grade and slot

The opening chances are 80% Low, 15% Medium, and 5% High. Once you get High, it has a 14.8% chance of one slot.

If it gets that slot, the option is Penetration 10.14% of the time or PvE All Attack Up 10.81% of the time. Adding the two accepted outcomes gives 20.95%. Those percentages apply to slotted High bracelets, not to every opening.

That makes the chance of a High bracelet with an accepted slot:

5% × 14.8% × 20.95% ≈ 0.155%

That’s around one in 645 per opening, before checking any varying stats.

Then, three maximum varying stats

Each varying stat has a 5% chance of the maximum value tier. Within that tier, the stat is All Skill Amp 30% of the time, Critical Damage 20%, or All Attack Up 50%.

For one line, either accepted maximum result counts:

• +6% All Skill Amp: 5% × 30% = 1.5%.
• +13% Critical Damage: 5% × 20% = 1%.

Together, that’s 2.5% per line. All three must succeed, so we multiply that chance three times:

2.5% × 2.5% × 2.5% = 0.0015625%

That’s one in 64,000 High bracelets with three accepted maximum lines, including every mix and ordering.

Putting everything together

Using the chances on the Sealed Turmacan’s Bracelet page:

5% × 14.8% × 20.95% × 2.5% × 2.5% × 2.5% ≈ 0.00000242% per opening

That’s roughly one in 41.3 million per opening: the right grade and slot, about one in 645, multiplied by the three maximum lines, one in 64,000. Requiring all three lines to be maximum is the biggest obstacle.

What does that mean over many openings?

The chance of finding at least one perfect bracelet rises with more openings:

A useful slot is much closer

If your goal is a High bracelet with a useful slot, accepting any varying stats gives these chances per opening:

• +50 Penetration: about one in 1,333.
• +140 PvE All Attack Up: about one in 1,250.
• Either slot: about one in 645.

Lower varying stats can still suit your build; compare the bracelet in the Build Planner to see whether it’s an upgrade.
