Guilds:
The game also has a guild and town system. Guilds can be formed by any number of players but you are required to meet a few guild level requirements in a certain number of days otherwise they are disbanded. This basically eliminates the chances off any small guild from participating in guild features. Guilds can earn points from just being online or by completing guild quests. With guild points, a guild can bid on a town and if they win, they gain control of the town for about 2 weeks. A guild with control of a town gets to change the tax rate of the town and can upgrade and maintain the town. At the end of their term, the guild has to bid on the town again to maintain control.

Mentoring and Crafting:
I put these two together because they are closely related and intertwined.

Mentoring allows a player Level 30+ to guide anyone below that level through the game. You can mentor 5 people who are below Level 30 at a time. They can remain with you past Level 30 and will give out large amounts of mentor points each level. A mentor can send their student items and teach them crafting skills if the mentor has the skill at Level 11 or higher. By teaching skills to other players, the mentor obtains exp on their skill instead of having to obtain it through crafting. As the student levels up, the mentor gains mentor points which can be traded in for items in Rome. Unfortunately with everything except the mentor points, you can do the same with friends and thus turns mentoring into a glorified friend system. Not only that, but some players are only in it for the mentor points and neglect the goals and purpose of the mentoring system.

Crafting needs to be at least Level 1 before you an make items (except Quest items). They can be learned from other players with the skill in Level 11+ or from NPCs in fixed locations. Level 11 and up crafting skills must be obtained from traveling NPCs or other players. Luckily the game provides a nice list of the people with the highest level in any craft that you can access. You can craft up to 15 equipment items at once and up to thousands of usable items at once. The most I ever did was 12000 arrows at once but you can still do more. In order to craft you either need the auto-craft skill or to fight. When you do either you get jobs and when you reach 100%, you obtain craft exp and you can select the items. You can cancel crafting but items are lost and you are not rewarded any exp. There are some items that can only be obtained through crafting. However, none of the crafts are profitable when considering the price of all the ingredients required and the selling price of the final product. It is something more suited for personal use.
