📋 About This Mod
Adds a new Sandevistan into the game which, in theory, has unlimited run time.
The cost of this infinite runtime however, is that V's health pool will be slowly deminished; the more V uses the Sandevistan per day, the greater amounts of health will be consumed.
After 5 minutes of use the sandevistan will be taking away 20% of health every 2. 5 seconds, and since health regeneration is disabled during sandevistan, V will have to come up with otherways to maintain his health to keep moving at super human speeds.
The sandevistan will disable itself if V's health gets too low, the less run time is left that day, the higher the margin of V's health pool will be left available before it puts on the emergancy brakes.
The sandevistan icon will decrement depending on how much run time has been used that day.
To reset the sandevistan run time, go to V's apartment and have a sleep. It will take 3 sleeps of 8 hours each to fully recharge it. (I thought about forcing them to be 12 hours apart; but decided against it)
The Edge Runner perk is required to unlock the full functionality of this cyberware; without the Edge Runner perk only the last 1/3rd of the runtime will be available; no amount of rest will fix that.
This mod does not change V's maximum health pool; the damage it does is akin to taking a bullet or any other damage type.
Once you've recieved Falco's Gift and are at or above Level 40, have a nap in V's H10 apartment.

[]The Sandevistan should be available from Vik's clinic, but this seemingly only works for new games started after the mod was installed, see comments for further information
At the end of the run time, when pushing the sandevistan beyond breaking point, this mod aims to make the player believe that V's grip on reality is going away. Flashing Lights, Strobing, Shaking; VFX is dialed up to 11.
If V has a cyberdeck installed V has access to overclock the Sandevistan
