...or can I keep it around, permanently buffing my Cyberdeck?
You need to use your Living Persona to compile, register and order your sprite.
You need to reboot both your Living Persona and your cyberdeck if you want to form your persona on your cyberdeck.
At that point your sprite will no longer buff your cyberdeck....
If a deck you have at least one mark on is not fully bricked then you can use a sprite for:
- Stability while it is repaired (so that the person taking the hardware test will always avoid to glitch it)
- Diagnostics while it is repaired (so that the person taking the hardware test will get extra limit and positive dice pool)
Unless you register the sprite you have about an hour before it is crashed by GOD
You can repeat thread low levels of Cleaner or Sustain a threaded Static Veil to increase the sprites longevity until you need to sleep.
You can also register (and re-register) it.
Unless it take an attack or sleaze matrix action this will increase sprites longevity until it run out of tasks.
