Game Description: Allows user to equip two weapons at once.
Job Traits are always active.
The Dual Wield job trait must be possessed, naturally or through Blue Mage spell selection, for equipment that enhances Dual Wield to have any effect.
Dual Wield only applies to one-handed weapons.
Combat Speed is calculated by adding the delays of both weapons and then reducing the combined delay by dual wield skill and then all forms of haste. Both weapons will swing at the same time, to accomplish this the delay on both weapons is standardized between the different delays your weapons may have (for example weapons at 225 and 175 weapon delay would result in both weapons being converted to 200 delay while weapons of equal delay will remain the same, 200 and 200 will stay 200. Calculating the individual speeds this way is important to understanding tp generation). At this point a % reduction based on your dual wielding skill is applied (25% for Dual Wield III, so in this case 400 * 0.75 = 300, and then any haste you have, 25% would be 300 * 0.75 = 225).
TP per hit is calculated using the reduced Delay. (except for Job Haste)
When dual wielding weapons with different Delays, the average Delay (Median of both wielded weapons x 2 minus Dual Wield %, Gear Haste and Spell Haste but NOT Job Haste) is used for the TP calculations; both weapons will gain the same TP.
Only the Weapon Skills of the weapon currently equipped in the main hand are available for use. If you equip two different types of weapons, you do not have access to both Weapon Skill sets at once.
The same applies to specific weapons that grant the use of weapon skills -- with Lex Talionis equipped in the main hand and Griffinclaw equipped in the sub hand at the same time during Campaign, you would only have access to the weapon-specific weapon skill associated with the main hand weapon; in this case, Glory Slash. The same goes for relic weapons such as Excalibur and Mandau.
