Magins buffs: If you want re-buff a character, in some cases the character who will recive the buff need in firt time clear his previous buff. If he dont do that he dont recive the buff.
Spitualist bugs:
Some one says that slow debuff of spiritualis doesn t work. And is partiality true. The debuff work but you dont will see in screen. The mob who recibe the buff apeart walk with normality. But he will not attack you in the time that should be walking slowly to you. If you kill him befor the drop will apear in the place where the mob should be walk with slow.
