Current Version: KMS 1.2.208

Adjusted Mastery: A factor added to DPS to consider the fact that different classes may have different mastery values; it effectively weighs the average damage from minimum and maximum range, thus is lower than standard %/s. A character with more mastery will have an Adjusted Mastery DPS closer to its absolute DPS.
Adjusted Mastery is always included in a character's %/s.
How to use:
Calculate your raw damage range and multiply with %/s. i.e. (4 * Mainstat + Secondarystat) * TotalWeaponAttack / 100 * %/s
Do not use your in-game damage range. That is wrong for the majority of characters since it includes total damage.
Divide out elemental resistance yourself (Hint: Divide by 2)

Boss: The %/s with the listed % Additional Boss Damage.

Hits/s, Max/s: Hits/Max damage per second based on the current attack setup, not necessarily the optimal hits/max per second possible, especially due to buffing. Any line of damage is considered a hit, even if it cannot reach the damage cap. Max/s is the maximum potential damage per second available. A skill such as Shadow Partner only deals a fraction of the damage cap as its maximum. Damage over time and summons deal their base damage assuming a range cap.

All buffs are assumed to be used unless they don't provide any useful bonus (namely, +Accuracy buffs)
