Tysis

The Tysis pistol spits out caustic darts that corrode their victims from within.

The Tysis is an Infested sidearm that fires Corrosive darts that deals damage over time supported by its incredibly high status chance, allowing it to wear down even the heaviest of armor with ease.

This weapon can be sold for ‍2,500.

Notes[edit | edit source]

The 81 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.
- If the dart punches through an enemy, they will instead receive 1 tick.
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]

A status chance of 260% may be obtained without any riven mods by combining Stunning Speed, Sure Shot, Carnis Stinger, Jolt, Pistol Pestilence, Scorch, and Frostbite (for a maximum of 305% with Embedded Catalyzer).
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.
- The Tysis may be modded for Radiation damage when dealing with Grineer, allowing it to deal extra damage to Napalms, Bombards and Elite troops.
Adding Blast damage makes this weapon ideal for battling Infested Ancients, as Fossilized enemies take more damage from both elements.

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 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). 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.
