Notes[edit | edit source]

  • This mod is given at the penultimate mission of The Sacrifice, automatically ranked to level 5. Additional unranked mods can be bought from Cephalon Simaris for ReputationLargeBlack.png100,000.
  • Sacrificial Steel is additive with similar mods. For example, a Galatine o.pngGalatine with a max rank Sacrificial Steel (full set bonus) and Mod TT 20px.pngMaiming Strike will have a 10% × (1 + 275% + 150%) = 52.5% critical chance on slide attacks.
  • Sacrificial Steel is essentially the Mod TT 20px.pngTrue 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.
  • Umbra mods have a unique Umbra Umbra polarity, whose matching polarity can currently only be found on Excalibur UmbraIcon272.pngExcalibur Umbra, Exalted Umbra Blade, and the Skiajati.pngSkiajati. It is possible to (re-)add an Umbra Umbra polarity to a mod slot but only through the use of Umbral Forma, which are unique rare rewards from Nightwave, so it is advised not to re-Forma any mod slot with an Umbra Umbra polarity.
  • Similar to other faction damage mods (i.e. Mod TT 20px.pngSmite 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).
  • When equipped alongside Mod TT 20px.pngSacrificial Pressure on Exalted Weapons, both mods will not show any set bonus, but set bonus effects will still be applied to the final stats.

Patch History[edit | edit source]

Update 28.0

  • Added the Umbra mods to Simaris’ store Offerings (available after The Sacrifice Quest completion)

Hotfix 26.0.7

Mod Changes:

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.

Update 23.2

  • Fixed Mod sets (Umbral, etc) not updating all values when equipping/unequipping Mods.

Hotfix 23.0.1

  • Mod is now link-able in chat. (undocumented)

Update 23.0

  • Introduced along with The Sacrifice quest.

Last updated: Hotfix 26.0.7
