The iron mass removes the skeletons attack speed and base weapon damage from leveling up the gem and replaces it with it's own damage and attack speed. An iron mass with maximum attack speed and damage rolls has 1.53 attacks per second and 195 average damage per hit.
A level 20 skeletons does (1,012 X .8) = 810 DPS
A perfect rolled hidden blade does (195 X 3) = 585 (585 X 1.53) = 895 (Note: Can go higher with corrupted modifiers.)
Scaling Damage
Skeleton damage normally scales with X 1.5 damage and X .8 attack speed. (1.5 X .8) = 120% of raw damage scaling.
Skeletons with The iron mass have X 3 = damage and X 1.53 attack speed. (3 X 1.53) = 459% of raw damage scaling.
459 / 120 = 3.825
The Iron Mass gives nearly 4 times the damage per second from flat added damage and the base weapon damage is much lower than skeleton damage from the gem. These 2 factors make added flat damage give higher damage per second than a skeleton build that doesn't use the iron mass.
