Weapon LoadoutsEdit

NotesEdit

  • Tysis needles retain their course after piercing their first target, possibly penetrating multiple targets without losing accuracy.
  • Tysis needles will be invisible if energy color is Black, making target leading harder as you can't estimate travel speed and deviation.

TipsEdit

  • A status chance of 182.50% may be obtained by combining Stunning Speed, Sure Shot, Jolt, Pistol Pestilence, Scorch, and Frostbite. However, there is no benefit to a status chance above 100%.
  • With its high status chance, the Tysis may be used as a softening weapon against Grineer. Corrosive effects stack, allowing another weapon to easily deliver the killing blow.
    • It is recommended to mod the Tysis for Radiation b Radiation damage when dealing with Grineer, allowing it to deal extra damage to NapalmsBombards and Elite troops.
  • Adding Blast b Blast damage makes this weapon ideal for tackling Infested Ancients, as Fossilized enemies take more damage from both elements.

TriviaEdit

  • The Tysis' needles may stretch targets if they are already pinned to the wall by another weapon's projectile (like the Boltor).
  • This is the second Infested weapon available on the Market. The first was the 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).
  • The head of the Tysis vaguely resembles the head of a Goblin shark.
