Weapon LoadoutsEdit


  • Every successful critical hit with the Hirudo will return 5% of damage dealt to the enemy as health to the player.
  • Each successful critical hit also increases the player's max health by 5%, referred to as Invigorated buff.
    • The health bonus lasts for 15 seconds, which refreshes everytime the player lands another critical hit while the buff is active.
    • The Invigorated buff can stack up to 5 times, for a maximum of 25% additional health bonus.
  • The Hirudo's max health bonus is scaled off of the Warframe's health at rank-0 and stacks additively with health mods like Vitality.
  • Both of Hirudo's special abilities also work when using quick melee.
  • Critical strike life steal bypasses sentient immunity.


  • Since it only requires Critical Hit to activate both abilities and it doesn't require to switch to melee and energy, mod with True Steel, Blood Rush or Maiming Strike to increase critical chance and any damage mods to increase lifesteal.
    • Berserker is useful in heightening one's attack speed in order to initiate more critical hits.
    • A fully ranked Blood Rush along with increased melee attack speed will easily allow one to heal faster than most enemies can deal damage.
  • On most Warframes, a 25% base health buff is very insignificant. Inaros, however, would gain 27.5 health per stack, up to 137.5 at max.
  • Using a warframe with higher armor values can help one stay alive while finding a target for the Hirudo's life steal.
  • Using this weapon with either stance equipped as Inaros can make charge attacks quite effective, as landing a charge attack on an enemy who remains alive after it connects will instantly transition into a finisher, which will activate Inaros' passive to gain health on finishers.


  • The Hirudo's name appears to be a bilingual pun in both Latin and Japanese;
    • Hirudo is the Latin word for "leech".
      • Similarly, leeches make up the subclass Hirudinea in their phylogenic classification.
    • Its name may also be a portmanteau of the Japanese words Hiru (蛭)which also means "leech", and Do (道, which may also be read separately as Michi), which can mean "way" or more loosely "doctrine", and can be found in the names of some Japanese martial arts (e.g. KendoJudo).
