(Stats)

  • Melee Attacks gain +20% Critical Damage per Cyst.

Curated and corroborated — the export and the wiki independently state the same effect. None of this mod's effect is counted in a build's stats.

  • Outside the engine: Melee Attacks gain +20% Critical Damage per Cyst.

Drain by rank

  1. R0 6
  2. R1 7
  3. R2 8
  4. R3 9

A matching polarity halves the drain, rounded up; a mismatched one costs more than no polarity at all.

(Sources)

Polarity, drain, rarity, compatibility and the card art come from the game export (snapshot 30 Sept 2026). Introduction version, tradability, mod sets and the drop tables come from the WARFRAME Wiki, CC BY-SA. Whether an effect is curated is our own judgement, recorded per mod.

Mods whose effect names the same thing and that fit the same place — melee. Naming a thing is not doing it: a mod here may only mention it in passing.
