Charge attacks from this scythe unleash a wave of acid that mutilates enemies and leaves a trail of corrosive sludge.

The Caustacyst is an Infestation b.svgInfested scythe that deals DmgCorrosiveSmall64.pngCorrosive damage, and its heavy attacks create a trail of sludge that damages and staggers enemies who walk into it.

Notes[edit | edit source]

  • When performing a heavy attack, the Caustacyst throws a toxic wave in the direction of the player's aim. This wave will travel up to 20 meters, dealing DmgCorrosiveSmall64.pngCorrosive damage to all enemies it hits. The wave will also leave behind a temporary trail on the ground that deals DmgCorrosiveSmall64.pngCorrosive damage to enemies that stand on it.
    • Wave range is not affected by Mod TT 20px.pngReach or Mod TT 20px.pngPrimed Reach.
    • Wave has infinite Punch Through.
    • The wave inherits any elemental damage from mods and can proc their status effects, having an approximated 10% base status chance.
  • Enemies hit by the wave are also staggered, making them vulnerable to melee finishers (default E ) and susceptible to stealth damage multipliers.
    • Enemies stunned by these pools do not have their alert status changed; enemies can be damaged by the pools and still be killed for stealth kills as long as their stun animation is still playing.
    • This allows players to launch a pool, then launch up to 3 more charge attacks before the enemy can become alerted.

Tips[edit | edit source]

  • The Caustacyst is an excellent weapon against the Grineer, allowing for DmgCorrosiveSmall64.pngCorrosive and DmgViralSmall64.pngViral to be used at the same time, as well as additional DmgFireSmall64.pngHeat to attack their health or DmgElectricitySmall64.pngElectricity for extra stunning capabilities.
    • Alternatively, it can be paired with DmgRadiationSmall64.pngRadiation for bonus damage against Alloy Armor, pairing with DmgCorrosiveSmall64.pngCorrosive's innate armor-peeling to allow for more general use against Grineer enemies.
  • The slow attack speed can be mitigated by equipping Mod TT 20px.pngFury (Mod TT 20px.pngPrime) alongside Mod TT 20px.pngBerserker and Mod TT 20px.pngGladiator Vice.

Trivia[edit | edit source]
