Modding the game

[Halivel]

From official side, it's against ToS, since you change game files so you can be warned and banned for this.
Still, system does not really check files so you can be okay with mods as long as you don't mention that you use them in game and don't post your screenshots with modded items on Official Forum or in Social Networks with your game info and probably with SE copyright label. Hovewer, there are mods that I personally find kind of dangerous for company from copyright side: those items ported from other MMOs like BDO or B&S specifically. I'm not against modding as an idea but seriously, people should turn on their brain when they do things.
