Keratinos

Combo-activated range claws

Released Aug 25, 2020

Keratinos is a mastery-rank-9 claw weapon whose heavy attack at maximum combo activates a three-minute extension to heavy-attack range and slam radius. Consider it if you are willing to build combo before using that timed reach benefit; outside that condition its listed base melee range is 1.7 m.

Keratinos GUIDE

Understand Keratinos

Useful when…

  • Close-range claw combat with Slash and innate Viral damage.
  • Building combo, then using a heavy attack to activate extended heavy-attack range and slam radius.

Timed range effect

The weapon's description specifies the condition: heavy attack at maximum combo. Doing so keeps the extended heavy-attack range and slam radius for 3 minutes. The supplied figures do not quantify the size of that extension, so the base range value should not be presented as the extended value. Its ordinary listed range is 1.7 m.

Attack profile

Normal attacks deal 87 Slash, 79 Impact, 45 Puncture, and 33 Viral damage, with 13% critical chance, a 2.1× critical multiplier, and 29% status chance. Standard slams deal 488 Impact damage out to 6 m with 50% falloff; heavy slams deal 732 Viral damage out to 7 m with 30% falloff. Each slam has 10% status chance. The special timed extension is tied to a heavy attack at maximum combo; do not assume it triggers from a standard slam.

Build and alternatives

Listed attack speed is 0.917 and heavy-attack wind-up is 0.8 seconds. The source lists no polarity, so it offers no stated matching-polarity slot advantage. Harmony is a scythe whose heavy attacks condense status-effect damage, Sarofang creates a heavy-slam vortex under a combo condition, and Tenet Exec has its own shockwave slams. Those are different mechanics, not equivalent replacements for Keratinos's timed range effect.

Limitations and tradeoffs

  • The range boost requires maximum combo and a heavy attack, then lasts 3 minutes.
  • Base listed range is 1.7 m; the size of the extended range is unspecified.

Common mistakes to avoid

  • Do not expect the range and slam-radius extension before reaching maximum combo and making a heavy attack.
  • Do not treat the three-minute extended range as permanent or assign it an unsupported numeric distance.
