Sacrificial Steel is additive with similar mods. For example, a Galatine with a max rank Sacrificial Steel (full set bonus) and True Punishment will have a 10% × (1 + 275% + 40%) = 41.5% critical chance.
This mod is given at the penultimate mission of The Sacrifice, automatically ranked to level 5.
Sacrificial Steel is essentially the True Steel mod with Legendary rarity and 5 more ranks. It is considered the same mod as its Common counterpart, and thus both mods cannot be equipped together.
The set bonus for Sacrificial Steel increases all stats given by the mod by 25% of mod's value per set pieces. At max rank with full set bonus, Sacrificial Steel grants a critical bonus of +275% and a damage bonus of +41.3% against Sentients.
This mod is equal to True Steel at rank 5 when using 1 set piece. It outperforms at rank 4 when using 2 set pieces.
Similar to other faction damage mods (i.e. Smite Grineer), the bonus damage against Sentients gets applied on top of the base damage and any added elemental damage of the equipped melee weapon (see Damage for complete mechanics).
The Critical Chance game has largely allowed Blood Rush to shine for active melee players, and with the ‘Steel’ series of Mods applying at the Base Critical Chance level, it’s led to players feeling they are obsolete. We are significantly buffing these Mods to give players a different option for Critical Chance builds. We want to give a more upfront Critical Chance and hard-hitting Heavy Attacks to builds that don’t rely on maintaining a high combo multiplier.
Sacrificial Steel increased from 88% to 220% Crit Chance (x2 for Heavy Attack) at Max Rank.
