Sudden Impact

Archmelee status chance mod

Released Oct 24, 2014

Sudden Impact increases status chance for Archmelee weapons by up to 60%. Consider it when your Archmelee weapon benefits from applying status effects and you have room in its standard mod slot.

Sudden Impact GUIDE

Understand Sudden Impact

Useful when…

  • Use on an Archmelee weapon when increasing status chance supports its status-focused setup.
  • Compare the single-stat bonus with elemental status mods if you also need a damage-type bonus.

Effect and fit

Sudden Impact provides +10% Status Chance at rank 0, +40% at rank 3, and +60% at rank 5. It applies to Archmelee, not ordinary melee or Archguns. This is a status-chance bonus; no weapon-specific proc rate is supplied.

Compare element and status options

Sudden Impact is a standard Archmelee mod with Vazarin polarity, base drain 4, and maximum rank 5. Cryo Coating, Infectious Injection, and Ion Infusion each list +60% Status Chance along with Cold, Toxin, or Electricity damage respectively, but each has Madurai polarity and a maximum rank of 3. They are alternatives to assess when the elemental bonus matters; their listed values do not establish a universal preference.

Ranking cost

Its successive rank steps cost 10, 20, 40, 80, and 160 Endo, plus 483, 966, 1,932, 3,864, and 7,728 Credits. The mod's maximum rank is 5. Rank it when the added status chance earns its capacity and resource cost; the exact drain at each rank is not provided.

Limitations

Do not place it in a standard melee build by mistake: its listed type is Archmelee. Also distinguish status chance from elemental damage; the elemental comparison mods combine both, while Sudden Impact lists status chance alone.

Limitations and tradeoffs

  • It increases status chance without adding a listed elemental damage bonus.
  • It requires investment through five ranks and occupies an Archmelee mod slot.

Common mistakes to avoid

  • Using it in a regular melee or Archgun build instead of Archmelee.
  • Confusing status chance with elemental damage or final proc chance.
