Focus item

Basics
Focus items are secondary weapons (sometimes called the "off hand") that increases the equipped character's maximum energy, between 3 and 12. They may also have other modifiers. Like all weapons, middle to high end focus items have minimum requirements from 0 to 13 in certain attributes for the primary stat (energy). If the character's rank in the required attribute is even one less than the requirement, a lower value is used for the respective stat. This value is 3 energy for white or blue focus items and 6 energy for purple or gold ones. There are also variable attribute Foci in Factions, which can be tied to the primary attribute from any caster profession.
