Strain Fever

Cyst-dependent damage mod for Helminth Charger

Released Dec 18, 2018

Strain Fever increases Helminth Charger damage by a percentage per Cyst. Consider it when your Charger build has Cysts to scale the bonus; without Cysts, the stated per-Cyst effect has no listed contribution.

Understand Strain Fever

Useful when…

  • Equip it on a Helminth Charger when the per-Cyst damage bonus supports your companion setup.
  • Compare the expected Cyst count and mod-slot cost before investing in higher ranks.

How does the bonus scale?

At rank 0, Strain Fever grants +10% damage per Cyst; at rank 3, it grants +40% per Cyst. The effect is explicitly tied to each Cyst, so the displayed percentage is not a flat bonus independent of Cyst count. No Cyst cap or formula beyond the per-Cyst wording is specified here.

When to consider it

The mod suits a Helminth Charger setup where Cysts are present and the Charger’s damage is a priority. Other Charger options do different jobs: Trample rushes through enemies and gains temporary melee damage, Health, and Armor per enemy hit; Strain Eruption adds Corrosive area damage when Maggots die. These effects are not direct replacements for a per-Cyst damage bonus.

Rank, polarity, and capacity

Strain Fever is a standard Helminth Charger mod with Madurai polarity, base drain 6, and maximum rank 3. The listed effect advances from +10% damage per Cyst at rank 0 to +30% at rank 2 and +40% at rank 3. Each step costs 30, 60, then 120 Endo, with 1,449, 2,898, then 5,796 Credits. The higher base drain and a standard slot make it worth comparing the rank gain against other Charger mods competing for capacity.

Limits and alternatives

Do not treat the per-Cyst value as the total damage increase without knowing how many Cysts apply. Proboscis is a pulling precept with listed damage, while Strain Eruption keys off Maggot deaths and current enemy Health; both are distinct effects and neither supplies Strain Fever's stated per-Cyst bonus.

Limitations and tradeoffs

  • Its listed bonus scales per Cyst, so value depends on Cyst count.
  • It has base drain 6 and requires Endo and Credits to rank.

Common mistakes to avoid

  • Assuming the listed percentage is a flat total bonus regardless of Cyst count.
  • Confusing Strain Fever's damage bonus with Maggot-death explosions or another Charger precept.
