ok so here is the copied epic 5 post from them on exactly what is going to change so without further adieu
We will have our E5 updates at least a month after Korea. This is to make sure any major issues have been found before we update. Any major issues found will delay our release.
Epic 5 Part 1
This is currently live on the Korean Test Server
Part 1 Contents
Pet Skill Renewals. There will be no more unimplemented pet skills. Angels, Centaurs, Salamanders, and Hawkmen get their own skills.
Pets' Buffs will not be castable on any random person. For example, their buffs might be limited to the Pet or the owner.
Pets will gain stats every level.
Cerberus and White Dragons will be added.
New Dungeon will be added.
New Armor: 2x R3, 1x R4, 1x R5
New Weapons: 16x R6
New Cloaks: 1x R2, 3x R3, 1x R4, 1x R5, 1x R6
New Helms: 1x R1 - R5
Decorative Pet System will be added. (Crab & Rabbit)
They will not do anything yet. In the future they might have some function.
Level Limits for Dungeons
Roaming System - Roaming Guards around the outside of the towns. Unclear what future functionality they will get.
