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

.
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.
