Corrupted Gem Level Increases/Decreases provide no damage changes

Hello, I know that this been posted before but after extensive testing I would like to post the information I have experience with getting +1 or -1 levels from corruption on skill gems.

1. Corrupting a skill gem and gaining or losing a level from corruption(Vaal gems/altar) affects the stats of the gems tooltip. This I assume functions as intended where you can see the stats/damage are affected by the increase or decrease in levels(comparing 2 gems;same level;difference gem level due to corruption)

2. The moment the gem is socketed into the skills window the increase or decrease is no longer factored into the DPS that is displayed or the tooltip damage #'s when clicking the arrow and seeing the breakdown of the skills.



I thought that maybe simply the skill window was bugged and not displaying the benefits or changes but the damage would be factored in, I spent a bunch of Vaal gems I added +1 onto a level 8 frostbolt which seems to have the best variance I could find for a spell, and -1 onto a level 8 frostbolt to test the actual damage. It took the same amount of time bringing a mob down to 50% hp with 1 version of the spell vs the other(testing many different mobs, same results).


There seems to be a bug or functionally wrong with the way the skill window and factoring in at least corrupted gem level increases and decreases. It is unfortunate because of the amount of currency wasted over the last few weeks on vaaling gems to achieve +1 when it has no benefits.
