Weapon dice multiplier

With Update 14, upper tier weapons in game, that previously had irregular damage dices (such as Green Steel weapons (History)) are updated in order to standardize them among various weapon types. New mechanic called Weapon dice multiplier or Base Damage Dice modifier is now applied to weapon dice roll. It is shown on the weapon description window in the format of "1.5[1d8]" and such, in this case, 1d8 is weapon specific dice roll and 1.5 is what is considered as multiplier (1.5-1=0.5 is what is considered modifier).

Weapon dice multiplier is applied to weapon damage before enhancement bonus and before critical hit multiplier. Spell buffs such as Deadly Weapons, and feats such as Point Blank Shot may have impact on this value.

With Update 29, randomly generated weapons gain additional [W] depending on their minimum level:
 * Min level 10 = +0.5W
 * Min Level 20 = +1.0W
 * Min Level 24 = +2.0W
 * Min Level 28 = +3.0W
