Variance

What is Variance?
 Formula: 1 - (Low End Damage/Top End Damage) = Variance  Variance is the difference between top end and low end damage on a melee weapon. Weapons spawn with a top end damage, and the low end is calculated using the variance. One handed melee weapons spawn with one of 5 variances, Two Handed weapons spawn with one of 6 variances. See charts below

How to decrease variance
By decreasing variance, you are increasing the possible low end damage on a weapon. This can be accomplished two ways. Granite Salvage can be applied to a weapon using the Weapon Tinkering skill to decrease variance by 20% of the current variance and will count as 1 tinker. Also, the Lucky White Rabbit's Foot can be applied to do the same, but does not require tinkering, or take up a tinker.
