Legendary items

One of things I mildly miss is ultra rare items.
Things you don't grind for, or get as a participation trophy.

Items that are easily recognizable, but largely obtained by luck.

Example of an item I would like to see.

Excalibur
Untradable Unique Artifact
Equipable any class
Ephemeral - Cannot repair, fades to nothing after 14 days
Ilvl - scales to level
Ability - increases party limit break gain by X%

Excalibur is the final lvl 50 relic for paladin
Job gear is called Artifact gear and it is Untradable
