Notes[edit | edit source]

  • The 81 Damage/Corrosive DamageDmgCorrosiveSmall64.png Corrosive damage is dealt in 3 ticks of 27 damage, over the course of 2 seconds. This allows a single dart to proc multiple times.
  • Tysis needles retain their course after piercing their first target, possibly penetrating multiple targets without losing accuracy.
  • Tysis needles will be invisible if the energy color is Black, making target leading harder as you can't estimate travel speed and deviation effectively.

Tips[edit | edit source]

Trivia[edit | edit source]

  • The Tysis' needles may stretch targets if they are already pinned to the wall by another weapon's projectile (like the BoltorBoltor.png Boltor).
  • This is the second Infested weapon available on the Market. The first was the MireMireInfestedSword.png Mire.
    • The Tysis is the first Infested sidearm to be non-clan exclusive.
  • The Tysis may derive its name from the suffix "-ptysis", which typically refers to spitting out substances (e.g. Hemoptysis would refer to spitting blood). It may also be based on Phthisis, the ancient Greek name for Consumption, AKA Tuberculosis, which was named such for "eating its victims from the inside".
  • The head of the Tysis vaguely resembles the head of a Goblin shark.
