Can anyone tell me if there exists a universal console in game (usable on any ship) that does a hull or shield heal? Looking at possibly playing around with the fleet Luna class, but don't want to completely lose the ability to pop an emergency protection power or heal power such as I have with the Vesta.
There is nothing that grants a heal that you could put on that ship. You could get a resistance bonus from a Resonance Cascade Modulator, or you could GTFO with a Impulse Capacitance Cell but there is nothing you can fit to that ship that will provide a heal.
While there isn't a universal console there are fleet embassy consoles that buff a specific science skill AND can come in plasma damage buff, chance to heal hull or chance to heal shields. They can also increase or decrease your threat generation.
