Bonus Specialists
As a general rule of thumb, it is a good idea to subdue and collect these bonus specialists early and often. All four specialists help reduce the amount of time needed to increase your party's strength, especially once you get to the point where you can create lots of new and fancy character classes. Note that the Broker and Mentor specialists do not affect bonus gauge gains.

Collectors
Collectors are interesting, if not so useful at first. The best use for collectors is to make several items of matching rarity value, so that your character gets the rarity bonus when equipping them. Note that these specialist actually increase the rarity value, which effectively decreases the actual rarity of the item. If an item has a rarity of 17 and you install a collector of value 1 on it, it's rarity value will become 18.

Collectors are obtained via the random rooms that you find in the Item World. If you stumble upon one, he will ask you if he is welcome to join your item, and will be subdued if you say yes. ''[research needed: the collector room may only occur on items that have open specialist slots? And if not, what happens when a collector joins an item that is already full?]''

Lovers
Lovers are a unique brand of specialist that auto-magically spawn on weapons that a character has used for a certain amount of time.
