The functionality of Inscribed Ultimatums has been disabled in the core game. They cannot be activated in the Map Device.
The Inscribed Ultimatum requires the specified item to be offered and have a set of pre-selected mods. Inscribed Ultimatums can be used in a map device to open a portal to the Utzaal Arena, which only contains an altar. The required item must be placed on the altar to start the trial. The outcome of successfully completing the Inscribed Ultimatum includes doubled Currency, doubled Divination Cards, or a random Unique of one rarity tier higher (see here for poorFishwife's research as of 3.14)
Unlike a regular Trial of Chaos, the entire arena is the trial zone (there are no out-of-bounds areas) and instead consists of one continuously spawning wave. Items and experience from killing monsters stop after a certain threshold.
Item acquisition
Inscribed Ultimatum has restrictions on where or how it can drop.
Can drop anywhere in a map containing an Ultimatum encounter, and can appear as a reward in Ultimatum encounters.
In Ultimatum league, Inscribed Ultimatums could drop in maps. They currently do not exist outside of permanent Standard and Hardcore leagues and can be obtained only by trading with other players in those leagues. However, since their functionality has been disabled, they serve no purpose other than existing as a memento.
Vendoring 5 Inscribed Ultimatums gives back 1, with the returning Inscribed Ultimatum being randomized and its monster level is the average of the 5 vendored Inscribed Ultimatums.
