I put together this simple guide since I've been see'ing alot of questions about how the upgrade system works.

Items needed to upgrade an item:

1. Blue weapon or armor peice that is unslotted.
2. Force core.
3. Blue weapon or armor peice of the same grade or higher of the item you want to upgrade.
4. Non PK status, so you can talk to the Core Alchemist :O

How to ugrade an item:

1. Talk to the core alchemist
2. Place your weapon or armor peice in the left slot.
3. Place the force core/s in the middle slot.
4. Place the catalyst(Blue weapon or armor) in the right slot.

Weapon / Armor catalyst bonuses (that i know of):

Blue battle helmets: HP
Blue Boots: Defense rate
Blue Chestpeice: Defense
Blue warrior weapon: Critical DMG

I know there are some things that I missed but this covers alot of the basic questions about upgrading.
