Original mod

I included the German and Chinese localization in version 2

Extended Immortality aims to provide a more challenging and rewarding experience for players who prefer to play immortal rulers. While playing as an immortal can be an enjoyable RPG-like experience in CK3, it also negates or trivializes many of the core game mechanics such as dealing with disease and injury, breeding high-quality heirs, and managing succession laws. This mod aims to fix that.

Features
Become immortal (decisions menu)
Share your immortality with others.
Adjust the visual appearance of any immortal's age to anything you want (right-click your character and choose "Select Visual Age").
Cleanse injuries and diseases at the cost of stress and temporary health penalties (decisions menu)
Become immune to disease permanently by gaining and cleansing yourself of six different severe ailments (decisions menu). A prompt in the cleanse screen will notify you of which ailments count towards the total.
Absorb the congenital traits of your primary heir (right-click your heir and choose "Absorb Genes"). More on this below.
"Blood" dynasty tree perks now affect trait inheritance chance for traits absorbed using the "Absorb Traits" option on your heir.
New game rule makes all immortality decisions free. essentially enabling a cheat mode (on top of the already cheaty fact that you're immortal to begin with).
