Update: Occasionally, when a gravelord servant uses an eye of death, several powered-up versions of the local enemies spawn in infected players worlds (these enemies are referred to as "black phantom enemies"). I will attempt to compile a list of what enemies appear and where. It could take a while though, as these enemies only appear rarely.
Update: It appears a gravelord's covenant rank does NOT factor in to whether or not black phantom enemies appear in other player's worlds. Also, I've fixed a few minor syntax errors.
As of writing this, the "black phantom enemies" are still not spawning all the time. Sometimes the enemies appear in a victim's world, and sometimes they don't. I have yet to find out what triggers this.
The "gravelord messages" are also functioning incorrectly. You'll rarely ever be warned when a gravelord is active in your world. However, when the message "disasters are gone after the defeat of the gravelord servant" appears, the gravelord's influence in your world will end (whether or not the gravelord was actually defeated).

After poking around this forum, I noticed most of the problems people have with the eyes of death item is that they aren't using them right. As such, I have spent the past 4 days researching, studying, and testing the eyes of death so as to make the gravelord covenant more accessible to everyone. You're welcome.
Be advised that the covenant IS bugged right now, but it is not completely unusable. For now, Eyes of Death only rarely spawn stronger monsters in other worlds (I've seen stories of it happening though, and I'm investigating that). Also, while I can't personally confirm this, it's possible Nito is supposed to give you more rewards past the +1 rank, whereas right now he currently doesn't.
By the by, since I'm only one guy, it's entirely possible I've made some mistakes. If you notice anything wrong or just want to add something, please say so and I'll fix it ASAP. This guide would be useless if it were wrong, ne?

EYES OF DEATH: What are they?
The Eye of Death is a Gravelord Servant's covenant-specific multiplayer item. In plain english, this is what they need to do terrible, terrible things to you.
However, unlike most other covenant multiplayer items, the Eyes of Death are one use each. In addition to this, a gravelord servant needs eyes of death in order to level up his covenant. So where do they get more eyes of death? By using them to kill you, of course. If they have no Eyes of Death to use, a gravelord can farm them from basilisks, but those have the nasty habit of cursing you.
The Eye of Death mechanic is very interesting, and in my opinion is one of the cooler tricks in this game. Unfortunately, it's not immediately apparent as to what they do or how to even do it, so you may think your Eyes of Death aren't working at all.

EYES OF DEATH: How do they work?
As previously mentioned, how an Eye of Death works is not immediately apparent, and getting the most out of an Eye of Death requires much experimentation. Unfortunately they are very scarce, and the best way to get more is by using them properly. It can be frustrating, which is why I've done all the hard work for you.
In order to use an Eye of Death in the first place, you must be human, and be in the gravelord servant covenant. If you are not in the gravelord servant covenant, you can't use an Eye of Death. Whether you are or not, you can't use one while hollow. This is important, since using one will make people want to kill you, and if they succeed you'll have to un-hollow before you can use it again.
First, let's go over what they actually do.
When you do use an Eye of Death, you are first asked if you want to use it to lure phantoms by spreading misery. If you choose no, the item will not be used. If you choose yes, then your eye of death will be used up and its effect will be active. When it's active, you cannot summon other players or challenge bosses, but aside from that you can move about freely. The effect will not cease until you die.
*
Be warned, the effect of an Eye of Death will also fade if you use a homeward bone or the homeward miracle. Also, since you can still lay down summon signs and be summoned while using an Eye of Death, being summoned will negate an eye's effect. You don't get the eye back, either. You can also invade while your eye of death is active, with the same result.
*
While the Eye of Death is active, other players in the same location and level range as you will become 'infected'. They will see a message telling them a gravelord has cursed them, and the only way to stop the ensuing disasters is to find the gravelord and kill him. While infected, a player may not invade other worlds and a special 'gravelord sign' will appear in their world. In addition, the Eye of Death is supposed to spawn horrible, powerful monsters in their world, but this is currently not working.
Where the gravelord sign appears in their world depends on where you are at the moment. When you use an Eye of Death, you essentially become the gravelord sign. As you move about, its location will periodically update in the infected players' worlds. This happens every 10 seconds or so.
Since the gravelord sign follows you, if you move to a completely different location the sign will follow you there. When it updates its location again, the players in your previous location will be released and players in your new area will become infected. As such, you can gravelord different areas without having to use another eye of death.
Gravelord signs have a very unique appearance, and can be distinguished from other signs easily. The 'letters' of the sign are spelled out with white bones, and a black mist exudes from around it. Even if you've never seen one before, you'll know it's a gravelord sign.
The gravelord sign has a number of unique properties aside from moving about. Even if a player is hollow, they can still see a gravelord sign. Especially notable, if a player has killed the local boss a gravelord sign can still appear in that area. They can invade you through your sign even if their boss is defeated.
If a player activates a gravelord sign, the game will inform them they are invading the gravelord's world as a spirit of vengeance. Since a gravelord can be invaded normally even while the Eye of Death is active, it helps to remember that players lured by the Eye of Death will spawn as spirits of vengeance, so if the gravelord wants more Eyes of Death, he'll need to kill the blue players.
It is important to note that as with all invasions, players can only invade a gravelord if he hasn't killed the local boss. If he has, the gravelord sign will not appear in other player's worlds until he moves to an area where the boss is still alive.
When a player invades the gravelord, their goal is to kill him. Expect no mercy, especially if the gravelord mechanic is ever fixed and they'll have to kill you to stop your monsters.
If the spirit of vengeance is killed by the gravelord, the gravelord will receive an Eye of Death along with a very small number of souls. I am not sure what formula this soul reward follows, but the end result is far less than killing a player via other means. As such, it's better to use Eyes of Death to collect more eyes than to farm souls.
When a vanquished player is returned to their world, if they find the gravelord sign again they can invade another time. There is no waiting period for defeated players; they can invade you immediately after dying, so long as they can find the gravelord sign.
In addition to this, multiple players can invade at the same time, up to 3 players at once. Since gravelords can't summon phantoms while using an Eye of Death and they can't escape the invaders by challenging a boss, gravelords must either be especially cautious or especially skilled to collect more Eyes of Death than they end up using.
If the players defeat the gravelord, they will be awarded with an Eye of Death and a paltry amount of souls. I'm not sure if this is what's supposed to happen, but it's what's happening as of now. As well, the Eye of Death's effect will cease, and in order to activate it again the gravelord must unhollow, then use another eye of death.
While using an Eye of Death, a gravelord can still be invaded by darkwraiths and darkmoons. Killing either type of invader will not award the gravelord with an Eye of Death, and since darkmoons also invade as spirits of vengeance this can be especially confusing. The best way to avoid darkmoon players is to not sin, and fortunately killing a player via Eyes of Death does not allow them to indict you.
There is a common belief that if a player dies while under the effects of a gravelord curse, the gravelord will receive half their souls. I HAVE NOT BEEN ABLE TO CONFIRM THIS. Despite all my efforts, the only time I have received new souls by an Eye of Death was by killing invading players.

EYES OF DEATH: Upgrading your covenant rank
So, what does a gravelord need all these Eyes of Death for? While it is nice to have an ample supply for personal use, what a gravelord really needs Eyes of Death for is upgrading his covenant rank.
By giving Eyes of Death to Gravelord Nito, the gravelord servant covenant can be upgraded. 10 eyes gives you gravelord servant +1, 20 more gives you +2, and 50 after that gives you +3, for a total of 80 Eyes of Death.
As of now, the only rewards for upgrading the covenant at all are an improved covenant-specific miracle at the +1 rank. I have seen rumors that there is supposed to be a suit of armor at +2 or +3, but I have been unable to confirm this.

EYES OF DEATH: Frequently asked questions
Unlike other FAQ sections where the poster simply adds questions they think will be asked or have already been answered in the original post, I intend to fill this with questions I am actually asked and answer them to the best of my ability. Some questions I will not know the answer to right away, so it might take a while. If another forumite answers the question before I do, I will credit them accordingly. If the question is already answered in the main section, odds are I won't answer it unless asked frequently enough.
Question #1: If I kill Nito, am I kicked out of the gravelord covenant?
Answer:

^^^ You remain in the covenant. You just can't level up in it, or rejoin if you leave.
I have not been able to test this for myself yet, but other, very reliable people here have said no, you aren't kicked out for killing Nito. You do lose the ability to rank up, however. I will test this myself, but it'll take a few days.
