Don’t bother, Kabbalist/Diev(and maybe even Krivis) are affected by the overlapping 2nd column buff instance bug since the end of June/begin of July and they didn’t even bother to write a simple response on that issue.
Same with Psychokino and Cataphract.
Not a favorite Class of the devs&players = slow or no bug fixes, lame balance changes, disregard of their self-set policies on Class - & skill treatment.
That’s a common trope in the Korean MMORPG genre nowadays, but it’s extremely bad in games like DN and TOS.
Be happy, we get nonsensesical issues fixed that nobody ever cared about since they didn’t affect gameplay of the majority of players. 
And if ITOS gets a new devastating bug, ITOS gets another maintenance on the same day on top for free. 
Not only do we get free frustration,bugs and trash events that make the NPCs look like vending machines strung with human skin, we might get another maintenance on top with free 14 days duration EXP Tomes as compensation(of course only up to 3 to prevent players to craft a 4x EXP Tome without duration). 
All hail the great adventure of new updates. It’s like spotting the differences, previous and post-patch, with surprising new “content”,“features” and “mechanics”
