Móresicil

"The black knives of the elves are used in their rituals of sacrifice to that Abominable thing they worship alongside the proper gods. They look like fragile glass, but they're anything but. I have two collections: a collection of móresicil, and a collection of thin, white scars that they've given me over the years."
~Archmage Dulacar, of the Brass Tower

Mechanics & Inner Workings

The materials that make up the knife expand its planar signature. This has three effects: beings from the Shadowfell, the Feywild, and the Dreamlands all immediately know that one is present. Secondly, the blade can cut through materials such as Adamantine which are nigh-unbreakable on the material plane but relatively weak in the Dreamlands. Finally, when it cuts flesh, it also cuts the spirit so long as a spirit is present.

Manufacturing process

The process is painstaking. The glass must be kept at a very high temperature or it becomes too hard to knap, and once it cools it cannot be reheated. This means the smith making the blade must remain in unhealthy temperatures for hours, sometimes days, in an area suffused with too much magic.

Significance

The signature device used in sacrifice, just having one marks the owner as either a member of the Airimossë priesthood or one of their mortal enemies.

Weapon

Very Rare Enchantment Requires Attunement

This weapon functions perfectly regardless of the plane it or its target is on. It ignores damage resistances, and targets killed by this blade cannot be resurrected for 1d10 years, as the bonds of their soul have been damaged and must heal.
On a natural 20 attack roll, all damage dealt by this weapon is converted to Force damage, and the victim must make an Intelligence Save DC 4+the damage dealt or their Maximum HP is lowered by the amount of damage dealt.
Once attuned to this weapon, the Abominable is immediately aware of the wielder and can communicate telepathically with them.
