Yagami Kira

Hi, good morning. I need some serious help from more experienced people on the subject, if not, I fear having to close their doors, the problem is the ability to Ministrel (3rd) Gloomy Day / Gloomy Shyness, which gives 3x more damage with specific skills classes knight / paladin and their evolutions, to the RK and RG, however, the ability of the Ministrel simply does not give any bonus, even gives the possible debufs as aspd reduction in motion chance to remove the hunt, and so on. .. Anyway, it is usable, but without effect, I do not know how to solve it, how to enable it, now test various emulators and dates, thinking it was a bug, but not resolvel, ie, it is even disabled, wish someone would test it on your emulator and tell me if it is functional and used the data folder of the emulator version, so I can change. Or even if it is a bug, help me a way to solve it. I am very grateful to those who help. Thank you.
