III. Doryani's Institute

Doryani's Institute is the tier 3 incursion room of Zalatl, Architect of Thaumaturgy.

The room contains a device called Lapidary Lens that "double corrupts" a skill or a support gem. The room also contains Thaumaturgy Vessels.

The chance for a Lapidary Lens to increase a gem's level by 1, without losing quality, is 20.83%, compared to the 12.5% with a Vaal OrbVaal OrbStack Size: 20Corrupts an item, modifying it unpredictablyRight click this item then left click an item to corrupt it. Corrupted items cannot be modified again..

1/4 * 1/2 * (2/3+ 1/6) + 5/8 * 1/3 * 1/2 = 5/48 + 5/48 = 20.83%. 
Respectively: odds of hitting level change on first corruption * The odds of it being +1 level change * (the odds of hitting non-quality change on the second corruption + the odds of hitting positive quality change) + the odds of hitting non-level change or a positive quality change on the first corruption * the odds of hitting level change on the second corruption * the odds of it being +1 level change

Noteworthy combination chances:

+1 Level and + Quality = 4.167% (3.75% for 23% quality)

+1 Level and - Quality = 4.167%

+1 Level and Nothing = 8.333%

+1 Level and Vaal if able* = 8.333%

-1 Level and + Quality = 4.167% (3.75% for 23% quality)

+ Quality and Nothing = 8.333% (7.5% for 23% quality)

+ Quality and Vaal if able* = 8.333% (7.5% for 23% quality)

Only Vaal if able* = 16.667%

  • If a gem doesn't have a vaal option, then it does nothing and it's chance is added to doing nothing.

Trivia

The room is named after Doryani, who was known for his thaumaturgy with virtue gems.
