Ep6 is not fully released yet plus we, the private server community, will not have access to it.
Unless Nexon doesn't encrypt the English version of ep6 like they have the Korean.
Yet anyway the full ep6 will have such things as a pet system, the craft system completed (I think? Hard to understand it), new skills (viewing the skill.sdata in notepad), higher level cap, and the other ep6 content we have/haven't seen.
What you are missing is the fact that Dimensions Crack is not the end game area.
The highest mob level is 86 and that is within the new ep6 content.
Most of the new items utilize new item codes completely.
Nothing is overwritten so you must be using something that isn't official and has been edited.
I can't remember off the top of my head, but for example type ID 16 is for light helms correct?
The new items use Type ID 80 or something like that. Like I said can't remember the exact numbers.
(although yes, some items still are within the old Types)
Ep6 content overall is pretty much like ep5. Except the extras included such as the pet system are what make it worth it.
Look around the official Shaiya site for the pet SS's they have them up

Umm I'm just me? O.o nothing special.
