On the new dungeon coming on patch that contains the new race, it will come a dungeon with only Bosses.
7, to be precise, the initial 3 are always the same, the following 4 you get out of 12 randomly.
These bosses drop materials used to upgrade the following gear to G15:

Upgradable equipment:

Level 90 – Holy Hall of Dusk – Helmet and Cloak
Level 95 – Crescent Valley – Armor and Weapons
Level 99 – Holy Hall of Dusk – Armor and Weapons
Level 100 – Holy Hall of Dusk - Weapons

(stats it has curently will be resetted, remember that)

When upgraded INITIALLY, HH things will get a more "heavenly" look, while CV stuff will get a more "demonic" look. Only look differs on weapons, but while on Armor, the HH upgraded ones increase their base defense by actual numbers, the CV one increases defense by % instead of numbers.

Upgrading costs the materials from dungeon, and Fortune stones, so you dont lose refine. It will cost more, the better refine and SOULSTONES your gear has.

The armor set, as usual, the more pieces you get, the more bonuses it gives you, getting a max of attack level +10 (aka +10% attack)

You will need to be level 100 to enter the new Dungeon where the mats drop, and you have 3 tries a day only, tho Im not sure if you can "trade" other dailies for extra chances on the dungeon. (+2)

If your gear is BOUNDED, it will still be bound to you, that wont change.
First you will only upgrade the WEAPON grade, getting no extra stats.
You will need to upgrade it again just for the 2 stats, a big one, and a smaller one, and this obviously requires less materials than the first upgrade.

Thats all I know for now folks, so no, dont think rank will be available for upgrade just yet, since it only came later on other versions because people obviously complained.

Anyway, will update info when I can. ^^

Introduction

With the return of the mythical undine clan, they've brought along a mysterious skill of "re-manufacturing". The special part of this skill is that the newly made equipment have the probability of retaining the original refines, sockets and soulstones bounded on it. However, you will need extra materials to do so. If the gamer does not wants to retain the original stats, they can re-manufacture without using those extra materials. The equipment produced will then not retain it's refinement, soulstones and the number of sockets will be randomized.

Overview of the re-manufacturing skill

Items that is qualified for re-manufacturing:
-Lv 95 CV weapon and armor
-Lv 99 HH weapon and armor
-Lv 100 HH weapon
-Lv 90 HH hat and manteau

The amount of materials needed is dependent on the refinement, number of sockets and the price of the soulstones. The higher it is, the more materials you'll need for them to be brought on to your re-manufactured equipments.

Regarding HH and CV equipments
For weapons, you can upgrade your weapon into any weapon of the same category.

I.E. CV Dual Hatchet is classified under Axe/Hammer type. If we were to re-manufacture a CV Dual Hatchet, we can choose to upgrade it into a Sledge Hammer, Pole Axe, Dual Hatchet or a Dual Hammer.

Armor wise, a top can only be upgraded into a top, a bottom can only be upgraded into a bottom. So on and so for.

Hmmm.. But it didn't say anything on the stats part though. It's more on the retaining of refinement, soulstones and sockets... :x
