I am at paragon 719. I still have not received the Iben Fahd

Something is wrong… I think I gained this item in the beginning of the game when I first started, and lost it somehow. What do I do to get the item? Tenascity

Iben Fahd’s Tenacity

Each and every chest you open in Iben Fahd’s sanctum has exactly the same chance to drop the Tenacity item.
That chance is 1%, as shown in-game…

Chance that a chest contains the Tenacity item = 0.01
Chance that a chest does not contain the Tenacity item = 0.99
Chance that none of X chests contain the Tenacity item = (0.99)^X

Some example values of X…

• Chance that none of 5 chests contain the Tenacity item = (0.99)^5 = 0.95099
• Chance that none of 10 chests contain the Tenacity item = (0.99)^10 = 0.90438
• Chance that none of 25 chests contain the Tenacity item = (0.99)^25 = 0.77782
• Chance that none of 50 chests contain the Tenacity item = (0.99)^50 = 0.60500
• Chance that none of 100 chests contain the Tenacity item = (0.99)^100 = 0.36603
• Chance that none of 250 chests contain the Tenacity item = (0.99)^250 = 0.08105
• Chance that none of 500 chests contain the Tenacity item = (0.99)^500 = 0.00657

There is no value for X which guarantees the drop, just that higher values of X make it increasingly unlikely that you won’t have found the Tenacity item after opening X chests.
