As we mentioned previously, artifact armor for both geomancer and rune fencer will be implemented during the next version update.
The plan is to release this new equipment for level 99 and I would like to explain why the development team decided to do this.
First, one reason is that Adoulin content is for level 99+ and as such the monsters in those areas are extremely high level, and trying to acquire level 50-60 gear in these areas just doesn't make sense.
The other major reason is that most of you are looking forward to wearing these new artifact armors to do battle with the monsters that lurk in Adoulin areas, so the development team made the decision to implement them at the proper level in which they can be used.
Item-level wise we are planning for these to be at least level 105, but as it is still in development, it may change.
With that said, the quest difficulty will match the item-level, so you might feel a bit nostalgic having to organize parties to hunt down this gear, much like you all had to do back in the day for your first artifact sets.
