Malenia in Elden Ring is especially weak to Frostbite and takes good damage from Bleed and Fire , while being resistant (but not immune) to Scarlet Rot.

Core Weaknesses

  • Frostbite :
    • She has low resistance to Frost, so Frostbite procs fairly easily.
* Frostbite both chunks a percentage of her max HP and lowers her damage negation, so subsequent hits deal more damage.
  • Bleed (Hemorrhage) :
    • Her resistance to Bleed is relatively low compared to many late-game bosses, letting you outpace her lifesteal if you apply it quickly.
* Fast Bleed weapons or weapon arts like Corpse Piler (Rivers of Blood) or other multi-hit Bleed setups are particularly effective.
  • Fire damage :
    • Guides list Fire as one of her main elemental weaknesses, and many strong Bleed setups incidentally deal Fire damage too.
* Fire-based greatswords and Ashes of War that add Fire can exploit this while still letting you stagger her.

What She Resists

  • Scarlet Rot :
    • Despite being the Goddess of Rot, she is resistant rather than fully immune to Scarlet Rot; it can work, but proccing it is slower and less reliable than Frost or Bleed.
* Rot is better treated as a supplemental damage-over-time rather than your primary game plan.
  • Poise / Stance :
    • She actually has low poise , so while this is not a “weakness type”, it means heavy hits and certain skills can reliably stagger or even knock her down, especially in phase 1.
* Combining stance-breaking with Frost/Bleed lets you chain critical hits and keep her from abusing her healing.

Practical Build Tips

  • For melee builds:
    • Use a fast Bleed or Frost weapon (or cold infusion) and focus on short, safe combos to avoid feeding her lifesteal.
* Consider heavy weapons or skills that cause knockdowns to abuse her low stance, then capitalize with criticals.
  • For casters:
    • Frost sorceries or spells that bypass her dodge “input reading” (like certain night sorceries) pair well with her Frost weakness.
* Fire incantations that create delayed explosions or large hitboxes can punish her when she commits to an attack.

Bottom line: stack Frost and Bleed , add Fire where you can, and use her low poise to keep her staggered so she cannot heal freely.
