- 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.
- 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.
- Adding Blast damage makes this weapon ideal for tackling Infested Ancients, as Fossilized enemies take more damage from both elements.
- 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.
