This mod is an official functionality from later chronicles specifically for Interlude. The lifetime of an item after its creation can be specified any with an accuracy of milliseconds.
It is very well suited for the “All in One” or Premium systems when the character is awarded additional capabilities for a certain period of time. The lifetime is tied to real time, not to game time, so it does not depend on the time spent in the game.
Quite a popular mod among my former customers of additions to their projects.
