Hello, hereoes of Lodoss Islands.
Wizard Labyrinth option "Fireball Critical Damage Increase" had an issue where the increase value was rolled back to before Labyrinth Rework Option patch.
It was supposed to be fixed last week, but we found that the fix was not properly applied in our last patch.
We will be fixing the issue in our next maintenance.
We apologize for any inconveniences caused, and ask for your kind understanding.
