In 12Sky2, the Master-Apprentice system allows players of Master level (M1 and up) to assist lower level players (112 and below).

Request: Starting the M-A System is very simple. Once a player reaches Master level, they can Shift+Click on a player level 112 or below and select "M-A Req."

Rewards: The Master will obtain Master - Merit points according to the Experience the Apprentice gains. They will also gain Experience from the Apprentice's kills. (Must be in range. If both characters are not within visual range, the Master level character will receive no benefits.)
Apprentice - 1.5x Exp when killing monsters.

Items:
1. Item Acquisition
There are two basic ways of obtaining items. The one is through NPCs. Players can use 12sky2 Gold (the 12 Sky 2 in-game currency) to purchase basic equipment from shopkeepers in their Faction's home town. The other one is from hunting and killing monsters to gain a wider variety and rarities of goods.

2. Other Methods
While players will most likely encounter the two above methods first, they can also attain items through trading with other players, or purchasing from another player's personal store.

3. Item Rarities

Common: Denoted with white text, lowest quality (items purchased at NPCs are typically Common).
Unique: Denoted with orange text, moderate quality.
Rare: Denoted with yellow text, high quality.
Elite: Denoted with purple text, highest quality.
Items Improvements

4. Enchanting Items
Equipment can be enchanted to offer a higher bonus to the character. Success leads to a % increase based on the material, but failure can lead to a 3% loss or even item destruction.
NPC: Blacksmith
Maximum Enchant: 120%
Enchanting Materials:

3% - Tin
6% - Dark Steel
9% - Black Steel
12% - Steel of Eternity
15% - Gold of Eternity

5. Item Combination
Another method of item improvement is combining items. Items that have the rarity Rare or Elite can be combined with other items of the same type and rarity (Elite items can also combine with Rare items one step lower).
NPC: Blacksmith

6. Item Crafting
Crafting consists of using multiple lower quality items to create an item of higher quality. Currently players have the option to combine a few different materials.
NPCs:
Blacksmith - Enchanting Materials and Jades
Elder - Archives

7. Item Upgrade/Downgrade
Twelve Sky 2 has the option to increase or decrease an item's level. This is handy if you have spent time, silver, and effort improving your equipment, or if you find a piece of equipment several levels too high for your character.
