A basic overview of what can be accomplished through the job system in Mafia Wars was outlined in the Basics. There are a few key concepts that are worth spending a bit more time on truly the get the best out of your Mafioso. Until recently, jobs were the principal way to gain experience and level up. You want to leverage the time spent doing jobs in order to maximize the benefit that can be gained in terms of skill points, monetary value, and items.
Job Mastery will yield you a skill point each time you complete a job's given mastery level. Once a Mastery level is obtained in all jobs of a given tier, the next level of job mastery opens up. Each job in each tier therefore has three levels of mastery and every job can yield three bonus skill points through the accomplishment of that Mastery. Every spare skill point achieved helps you level even faster regardless of the strategy that is employed for leveling.
Along with skill points, in each City there are also rewards for fully mastering a job tier. In New York, these items are key to staying competitive.
|Pistol Bayonet||+4% damage dealt in fights|
|Roadster||-7% damage received in fights|
|Golden Skull||a 30 second reduction on your health regen timer|
|Money Plate||a 5% discount on property purchases|
|Chainsaw Bayonet||a 30 second reduction on your stamina regen timer|
|State Senator||a 5% discount on property repairs|
|Helicopter||a 30 second reduction on your energy regen timer|
|Private Island||a 5% bonus on job experience|
|Golden Throne||2x the energy regenerated per regen period|
In Cuba completing a job tier rewards a unique item that is best in class for the category of the item. Mastering all of the job tiers in New York should clearly be the first priority as the Golden Throne for mastering the Boss level is the singularly most useful item in the game.
Every job tier has at least one, if not more collections that can be gained. On the Inventory tab you can select Collections & Vault in order to view what pieces you have and which ones you still need. You can trade away collection pieces, but they can not be stolen. You do not get the benefit from vaulting a collection until you actually click on the Vault button after getting at least one of each item.
After a collection has been vaulted, if you manage to collect another full set of that collection this can then be vaulted again to yield boosts. These boosts are one shot items that are immediately applied the next time an action is taken that would benefit from it. For instance, if you have a boost for reducing the amount of energy spent on a job, your very next job will use this boost. Hence, with the exception of robbing and fighting defense, you will want to hold off on vaulting your extra collections until you actually want to use the boost it will give you.
If you are trying to talk friends into playing the game, offering them full sets at the outset can be greatly beneficial. A player does not need to have a specific job tier unlocked in order to be sent the collection, though they may not be able to immediately vault it. The collections that yield extra energy points can be especially useful to a new player. Boosts can be similarly traded, but do not provide quite as much benefit to the receiver.
