Ghosts can only transmat and heal and rez us. That’s all they do. They are the most one-trick of one-trick ponies.

In regards to our own abilities. I think the ghost is the key that unlocks them. So we should be able to use them without our ghost nearby. But ghost is for sure responsible for healing and rezing. Don’t know if the connection to the light is severed when the ghost is destroyed/deactivated but the light is still there in the guardian since a guardian in the savathun‘s song strike lost his ghost before his light was extracted.

I think the ghost is what allows us to regenerate health and is likely the reason why guardians don’t age or need to sleep or eat. However I don’t think they are the reason why can use our abilities.

Drifter's Ghost turns red and freezes things. I wish they would have gave our Ghosts powers, but we'll see how these finishing moves do.

Recovery (heal) and rez. And black hat.

Yes, loosing your Ghost doesn't mean you loose your light. You can still do all the crazy stuff you can do as a Guardian but you're as fragile as a regular human being

We could still do literally everything we can now except be revived by our Ghost.

Oh we are heavily reliant on them but the lore is hazy, not a lot of concrete facts. Just implied through examples in the lore. Lemme breakdown what I know and think. We don’t need our Ghost to like us to retain our power, there is a Ghost killing Guardian out in the Shore still around. His Ghost said he regretted not paying more attention to his scans that told him the man wasn’t mentally fit to be revived. So this Ghost choose to make its Guardian. Another story tells how during the scan of a person the Ghost lost control and felt like the revival was done through it rather then by it. So the selection for this one was “destined”, [u]so long as the person was actually scanned in the first place.[/u] A nice little random chance element that wound up having a [i]major[/i] impact. Note this for later. I feel like the conversations between Bad Guardians and their Ghosts leaves room for a Ghost to somehow discontinue. Either by distance or some other cutoff mechanism. All known instances of Ghosts abandoning their Guardians, but it not being destroyed, involved Bad Guardians who have Dark power. So we can’t tell what effect distance might have. Distance wise...let’s look at the ones I can recall. Aunor had hers taken within the City, Rezzyl left his on the surface of the Moon and went down into the Hive labyrinth. Osiris seems to be the longest distance example, nothing is implied he lost his powers when Sagaria was wounded or away from him but we don’t know since we never see. He did survive and maintained his power within the Forest during the interim, so I’d have to say he had his power. Just not his revive since she was gone. Most times when the two get separated one or both gets destroyed. So it’s a hazy area of lore. Dredgen Yor didn’t destroy his Ghosts just sent it away. It never came back as far as we know to revive him, meaning it moved on. Some Ghosts are known to abandon looking or lose their Guardian and don’t look for another. Jaren Wards Ghost took the place of Shin Malphurs. Shin Malphur is noted case above. In order for “grown up” Shin to be able to become the legend he is today he had to be alive right? So the Ghost scan revealed something About the state of the soul [i]in the future[/i] Which is an awesome and sets up several unique instances; a child being chosen, a Guardian losing a Ghost and becoming normal and living a normal life, a former Guardian being selected by a Ghost, a Ghost having a second Guardian. Which sets up some flexibility for Ghost Guardian pairing rules. All life has a “spark” but those Sparks not exactly like our Light. It’s more reminiscent of the soul of a living being. This spark is actually quite peculiar. The Ghost who revived Shin when he was young didn’t understand how his moral character could be judged already. That implied predestiny in souls is pretty important. When you consider Ghosts are also called [i]companion souls[/i] in relation to our Guardians. Souls that were mechanized instead of born, made to find peo D1 lore about Ghosts is...interesting...and freaking weird. Hard to know how much still applies. Revival and healing seem to rely on them. Transmit is possible without them but we or someone else would have to. I think however that they rely on telemetry from the Ghost. Coordinates and all. We would have to have something on us like a transponder to mark locations for stuff coming and going. However, in regards to them enabling abilities, they don’t really “do “ anything to do that. Once they revive us we are [i]bonded[/i] and always have our powers, we just need to learn them and grow our strength. Destroy the Ghost, we become mortal. By extension of the Traveler being caged, there should be a way to cage a Ghost to disrupt our Light. It’s noted that as the Light becomes stronger so too do Ghosts. They are now tougher to kill, as revealed with Forsaken. That’s why Ghosts stay hidden in combat. They are what makes Guardians possible.

Why can't Ghosts attack? If they're so important, shouldn't they have some sort of self defense? Maybe a laser beam attack or something?

Same thing that happened in red war for abilities but with inventory who knows bungie decided to get rid of all our stuff regardless

I think when you start whipping out butter and a Sock and whisper at your ghost its time to draw the line

I say if your talking Rubik's Cube breaks, you can't cross the street.

As far as abilities it's really just first-aid. Resurrection and health regen. Ghost also does a lot of other important things but as far as our actual Guardian abilities it's just that.

Our ghosts are really just there to open doors, give us information, provide a flashlight, and allow our resurrection when we die. All of our abilities are independently sourced from the traveler, and don't depend on the ghost in order to function.

We don't need the Ghost to use our abilities, Ghost revive and heal use but there are abilities that do can do the dame like sungsinger self rez or that one hunter who got separated from his ghost but was still able to use the void bow. A Ghost cannot live without periodically returning to the traveler for unless it finds a guardian, then it can stay away indefinitely, an example would be the Ghost who stowed away onboard a Guardian ship to mars in search of it risen but was running low on light because it was to far from the traveler and did not yet find a Guardian.

I don’t know of any reason for the ghost except healing and resurrection that was made official by the lore.
