Thalys

Heavy scythe whose repeated attacks plant Void shards that damage previously marked enemies.

Released Jun 25, 2025

Thalys is a heavy scythe built around planting Void shards in enemies: each new shard causes existing shards to damage their hosts. That makes it worth considering when you can keep landing attacks on enemies to build this repeated-hit effect. Its regular attacks are slower than several weapons, while its heavy attack and heavy slam have separate listed damage values.

Thalys GUIDE

Understand Thalys

Useful when…

  • Keep striking the same enemy to make each new shard trigger damage from existing shards.
  • Use normal attacks for its Slash- and Puncture-based melee damage.
  • Use the heavy slam when area damage is useful, accounting for its listed falloff.

How does the shard effect work?

The description states that the weapon plants Void shards in enemy flesh, and that each newly planted shard causes existing shards to inflict damage on their hosts. Treat repeated hits as the supported practical condition; do not assume a particular cap or damage formula.

What are its attack properties?

Normal attacks deal 300 listed damage: 210 Slash and 90 Puncture, with 30% critical chance, 2.2× critical multiplier, 24% status chance, and listed speed 0.917. Regular slams deal 600 Impact in an area, with falloff to 8 m and 50% reduction. Heavy slams deal 900 Blast in an area, with falloff to 9 m and 30% reduction. The listed heavy-attack damage is 5,400; it is separate from the 900 heavy-slam figure. The weapon has 2.8 m range and a 1-second wind-up.

Who should consider it?

At Mastery Rank 12, Thalys suits players interested in a melee weapon with a repeated-hit effect and a heavy-scythe profile. Its 30% critical chance and 2.2× multiplier support considering critical investment; its 24% status chance and mixed Slash/Puncture damage offer another direction. Which investment makes sense depends on the build, and the listed base properties do not establish final damage or a shard-focused mod formula.

How does it differ from other candidates?

Arca Titron builds electron charges through successive kills and releases them on slam attacks, so its payoff depends on kills and slams. Cerata is a glaive, while Skiajati is a Nikana; neither comparison entry describes Thalys's shard interaction. These are differences in weapon type and stated mechanics, not evidence that one is a direct replacement for another.

Limitations and tradeoffs

  • The listed attack speed is 0.917 and the heavy-attack wind-up is 1 second.
  • The shard interaction is described qualitatively; no shard cap, duration, or damage amount is given.
  • Its regular and heavy slams deal different damage types and have different falloff distances.

Common mistakes to avoid

  • Do not assign a shard damage value, duration, or maximum count; none is specified.
  • Do not treat the heavy-attack damage value as the heavy-slam value.
  • Do not assume slam attacks plant shards; the description does not identify which attack modes apply them.
