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). Foci with attribute requirements of 0 have been observed with an energy bonus of up to +6, foci with the maximum energy bonus of 12 have bene observed with requirements as low as 7, all maximum energy collector, crafter and unique foci have an attribute requirement of 9. 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.
