Viral Quills

A Panzer Vulpaphyla precept that fires Viral quills and can add Spores to targets already affected by Viral Status.

Released Aug 25, 2020

Viral Quills automatically launches quills at nearby enemies, dealing Viral Damage with a chance to inflict Status; hitting a target already affected by a Viral Status adds a Spore. Consider it for a Panzer Vulpaphyla build that benefits from this repeated companion attack and its conditional Spore effect.

Viral Quills GUIDE

Understand Viral Quills

Useful when…

  • Adding a companion attack against enemies within 20 meters.
  • Applying the precept's Spore effect to targets already affected by Viral Status.

Quills and the Spore condition

At max rank, the precept launches 6 quills at enemies within 20 m. Each deals 60 Viral Damage with 40% Status Chance, and the attack has a 4-second cooldown. A Spore is added if the target is affected by a Viral Status. At rank 0 it launches 3 quills, each dealing 15 Viral Damage, with a 10-second cooldown; the Status Chance remains 40%.

Rank and slot

Viral Quills is a Rare Panzer Vulpaphyla standard precept with Penjaga polarity, zero base drain, and a maximum rank of 3. Its listed costs rise from 30 Endo and 1,449 Credits for ranks 0 to 1 to 120 Endo and 5,796 Credits for ranks 2 to 3. Ranking adds quills and damage while reducing the cooldown; the listed Status Chance remains unchanged.

Related Panzer precept

Panzer Devolution describes what the companion does when downed: it devolves into larval form, attacks with quills, and regains true form after 30 seconds. That is a different condition and function from Viral Quills' periodic attack on enemies within range.

Limitations and tradeoffs

  • The precept has a cooldown, which is 4 seconds at max rank.
  • The Spore addition requires the target to already have a Viral Status.

Common mistakes to avoid

  • Assuming the Spore is added to every target regardless of Viral Status.
  • Ignoring the 20 m range and cooldown when expecting repeated attacks.
