The Vasca Kavat is a Kavat Companion carrying the infectious Vasca Virus. Vampiric in nature, its precepts

Acquisition
The player must have completed the Howl of the Kubrow quest in order to have an operating Incubator on the Orbiter, and have installed the Kavat Incubator Upgrade Segment whose blueprint can be obtained from the Clan Dojo's Tenno Lab research or dropped by Hyekka Masters, or purchased fully built from the Market for 
 175. The player must also have 10 Kavat Genetic Codes from scanning Feral Kavats on the Orokin Derelict tileset on Deimos using Codex Scanners or Synthesis Scanners, and a built Incubator Power Core whose blueprint can be obtained from the Market.
Rather than being generated from the Incubator, the player must have their owned Kavat become infected by wild Vasca that appear at nighttime in the Plains of Eidolon. The wild Vasca can also be lured out via Conservation where Master Teasonai sells the Vasca Kavat Lure for 
 3000 and Vasca Kavat Pheromone Oota for  200. Once the player's Kavat is attacked by the wild Vasca, it will become infected, indicated by a red overlay. Vulpaphylas cannot be infected. If the Kavat is downed in one hit by the wild Vasca, it will not return infected.
The player must then take their infected Kavat back to the Orbiter's Incubator and use a Genetic Code Template on them. To ensure that it will be specifically a Vasca Imprint, rather than an imprint of the original Kavat's breed, the wording of the confirmation dialog should read "Creating a pet imprint will consume a blank imprint and cure your Kavat of the Vasca Virus. Continue?" Selecting YES will start the imprinting process, which will yield a Vasca Imprint while also removing the virus. As this is creating an imprint, available imprints of the Kavat are required and also used up. Two imprints are necessary to guarantee the creation of a Vasca Kavat.
Note that the infection will be removed as the imprint is created; as such, the infection process needs to be repeated to get the required 2 imprints. This process can be streamlined by having two Kavats and infecting them both before creating the imprints, bypassing the wait for the first imprint creation before obtaining the second infection.
To remove the infection without using a Genetic Code Template, the player must have a Vasca Curative, sold by Master Teasonai for  500. It is a gear item which must be equipped and used in a mission.
Alternatively, the Vasca Kavat Starter Kit can be bought from the Market for  105. This bundle includes two Vasca Imprints, the 10 Kavat Genetic Codes, Incubator Power Core, and an extra Genetic Code Template.

Update 37.0 (2024-10-02)
- COMPANION REWORK (PHASE 2)
Phase 2 of the Companion Rework is here! Your Companions all cheer!
Our overall goal with this update is to address Quality of Life and Balance problems that have become apparent over the last few years with Companions.
So letâs dive in!
Beast Companions Gain a Moddable Weapon
First up, we've added a separate weapon slot to all your Beast Companions (except for Hounds, who already have one).
A common complaint that we have heard is that there's not enough Mod slots for Beast Companions that don't have a separate weapon, because the same slots are used by Precept Mods, survivability mods, and damaging mods. We absolutely agree that this was a problem!
Hereâs what you can expect:
- When you login you will automatically receive a Beast-specific weapon for each of your Beast Companions. This does not take inventory space or cost you any resources.
- Beast weapons gain Affinity and rank up, but they do not contribute towards your overall Mastery.
- Posture Mod slot for Beast melee weapon alters overall behavior, gives extra capacity for modding.
As a result of this change, different Beast Companions now have updated unique weapon stats based on their individual type instead of being identical:
- Kavats: Previously ALL types of Kavats: Damage 80, Status 7.5%, Critical 20%/2x
- Vasca Kavat: Damage 110, Status 25%, Critical 15%/2x
Please note that, while these weapons are now moddable, we did not add them to the Riven system nor do we have current plans to. With so many extreme changes to Companions all at the same time, we want to let the dust settle a bit before evaluating.
AI changes
- Beast Companions would previously follow behind you while moving, which made it harder to notice them around and put them further away from enemies when combat started. They will now try to lead you instead, staying a few meters ahead while you are moving so they are ready to attack when combat starts.
- Beast Companions would previously choose targets in a complete circle around the player. This means that when using their abilities or making attacks, they weren't even on screen so it was hard to appreciate them being useful. This has been tuned so that Beast Companions will prefer to choose targets that are near you and in your field of view.
- When selecting a new target to attack, Beast Companions now gain a speed boost on their way to the target while off-screen (to reduce the time it takes them to engage).
- Improved animations while following the player through bullet jumps and double jumps so that they animate more quickly and fluidly.
- Decreased the required distance from Beast Companions to their owner to trigger a teleport and reduced the minimum time between teleports so they can more easily keep up with you if youâre bullet jumping at mach speed! They will also now disengage from enemies faster if you are moving quickly through the map.
- Improved Beast Companion targeting logic to better match their combat behavior and prevent cases of them âstallingâ when trying to decide on their next target. Also tweaked the range at which theyâll attack enemies to ensure theyâll actually hit them!
Changes to Companion Precepts
Many Companion Precept effects are currently too small or too brief to be really beneficial. We want your choice of companion to feel more meaningful and for your Companion to contribute in a more visible way, so there are a whole lot of buffs to get through.
- Draining Bite (VASCA Kavat):
- Inflicts 5 stacks of Slash stats on the victims, based on 150% of your Vasca's weapon damage.
Update 34.0 (2023-10-18)
- COMPANION STAT CHANGES
Two broad changes have been made with regard to your Companion's base stats to increase their staying power:
1. Health, Shields and Armor have been refactored across the board.
This simple numeric buff was made with the goal of increasing Companion survivability. This also means that the choice of whether to use, for example, Enhanced Vitality or Linked Vitality, will depend on your Warframe choice instead of the Linked Mod always being strictly superior.
2. Non-Sentinel Companions now gain their full Health and Shield values immediately when you acquire them.
Historically Health and Shield values would increase as your Companion ranked up, which you could see as "Rank Bonuses" in the Upgrades screen. We've removed this behavior and simply given Companions what would end up being their Rank 30 values at Rank 0. This should let you immediately take your Companions on more difficult missions after earning them!
Including both the removal of Companion Rank bonuses, and the base increase to stats, the following lists the stat changes for all Companions at Rank 0:
Revised Kavat Stats:
- Vasca Kavat: 310 Health (from 80), 270 Shield (from 70), 200 Armor (from 50)
