The Iron Mass

Mechanics

Buff/Debuff

Recently refers to the last 4 seconds.

Math

Base Damage

Summon Skeletons normally have their own weapon with .8 attacks per second that gains base damage as they level up. A level 20 skeleton has 1,012 average damage per hit.

The Iron Mass removes the skeletons' attack speed and base weapon damage from leveling up the gem and replaces it with its 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 lower than skeleton damage from the gem at level 22. These 2 factors make added flat damage give higher damage per second than a skeleton build that doesn't use The Iron Mass.

A few examples of flat minion damage may include:

Added Chaos Damage Support
Abyss jewels with Minions deal # to # additional [damage type] Damage
Auras with flat damage such as Envy.
Rallying Cry
Summon Carrion Golem have a buff that increases other minions' flat damage. This can be boosted by things like:
- 150% increased Effect of the Buff granted by carrion golems from the Eternal Labyrinth helmet enchantment.
- (#)% increased Effect of Buffs granted by your Golems from multiple sources. See golems.

Item acquisition

The Iron Mass can rarely replace a Curio Display in the final reward room of Alternate Quality Gems Blueprints e.g. Blueprint: Repository and Blueprint: Tunnels and cannot be chanced.

Version history

Version	Changes
3.20.1b	Updated various descriptions to clarify which stats only apply to Summon Skeletons, and which apply also to Vaal Summon Skeletons (such as the modifier on Alberon's Warpath). Melee Skeletons from the Vaal Summon Skeletons are now referred to as "Soldiers" rather than "Warriors" in descriptions.
3.12.0	Introduced to the game.
