Amulets of life saving only generate when a lich generates, either in its inventory or somewhere else on the level where it first generated. Each amulet is tied to its lich, and the lich can only be permanently killed when its amulet is destroyed (including by the player using it up to save their own life, but not limited to that; any method of destroying it such as looting it from a cursed bag of holding would work). If the amulet remains intact, the lich will eventually resurrect.

If a lich is genocided, any amulets connected to liches of that type aren’t destroyed, but stop being effective to save lives. Possibly there should be some visible indicator of this, such as the amulet being cracked. If all liches are genocided, then no amulets of life saving will work.

Not specified what would happen if an amulet of life saving is wished for; probably either the amulet doesn’t work, or it spawns a random lich it’s connected to somewhere on the level.

Each Rider has the ability to use their attack to destroy items you’re carrying that are antithetical to their purpose, which replaces their normal attack.

• Death destroys amulets of life saving.
• Pestilence destroys all types of healing potions.
• Famine destroys horns of plenty and food items.

Throwing an amulet of life saving at a statue may revive it, which uses up and identifies the amulet.

Place gear suitable for a wide variety of pets in the Healer quest (mostly in the home level), and an amulet of life saving in Hippocrates’ chest.

A cursed amulet of life saving, if saving you from HP-loss death, will restore a completely random amount of hit points.

Decapitation is not protected by an amulet of life saving, since the amulet just falls off your neck. Alternatively, keep the life saving, but give a special message about the amulet crumbling to dust as it falls off your neck.

The amulet of life saving does not restore the hundreds of hit points it can currently restore; it restores something on the order of 6d10, enough to buy time to quaff a potion of full healing, but not enough to repeatedly put on more amulets and let the massive HP store run down on its own.

When either you or a creature is brought below 10% HP while wearing an amulet of life saving, it “begins to glimmer”. Note that something should be done to prevent this message from appearing in rapid succession if the wearer heals back up around 10%. Also, ideally, something should be done to prevent the player identifying the amulet of life saving by hurting themselves deliberately until under 10% HP.

Cursed amulets of life saving allow you to remain in the game, at the cost of bringing you back as a skeleton.
