I've always thought that heirs should be more useful and interesting in this game. This mod is me trying to achieve that.

With Useful Heirs, you can:

- Change the leader class of your heir.

- Designate any of your leaders as your heir.

- Abdicate the throne in favor of your heir.

- Play with a new civic, Adoptive Dynasties.

---

- Former Heirs won't stick around. Politically speaking, it would be pretty wild.

- In relation to my Civil Wars mod, heirs have unique rebellion mechanics. Check out that mod for more information.

--

- You can designate any leader as your heir for 2 years worth of Unity. This will also cause your planets to lose some stability for 10 years. -10 Stability for the capital, -2 Stability for every other planet.

- There is a new civic, Adoptive Dynasties, that grants +5 base Stability + 0.5 Stability per Councilor level for +10 Stability at level 10. It also allows you to designate heirs without the Stability hit or Unity cost. If a dynastic heir ascends to the throne while you have this civic, you will lose the bonus stability. The capital will lose 15 stability and every other world will lose 10 stability. Practically, this means that you can go from +10 to -10 on non-capital worlds, for a 20 stability hit.


- For species without the Venerable trait: If your leader is 50 years of age or older when they ascend to the throne, your heir will now be limited to being between 15 and 47 years younger than them. So, for example, if you have a ruler who takes the throne at 118 years of age, the heir that spawns will be between 71 and 103 years old.

- For species with the Venerable trait: If your leader is 100 years of age or older when they ascend to the throne, your heir will now be limited to being between 30 and 94 years younger than them. So, for example, if you have a ruler who takes the throne at 203 years of age, the heir that spawns will be between 109 and 173 years old.

- The AI will use the feature to designate their heir as a leader.

- Starting at age 70, an AI will begin to consider abdicating the throne to their heir every year, unless they are immortal. The chance that they will abdicate increases every five years. The abdicating ruler may also decide to become a regular leader in the empire. This isn't really relevant to the player, but if you like RP and stuff like I do it's neat.

If you're also using my Civil Wars mod, disinherited heirs can cause problems. The consquences may take years to occur, such as when the old leader dies, or they may occur quickly. This can be mitigated by Adoptive Dynasties, but even then once an heir is appointed they will not take kindly to being disinherited. Disinherited heirs may also try to run away to a foreign empire. Foreign empires will have the choice of whether to grant them asylum. If they accept, the heir will become a leader for that empire, and they will gain a Casus Belli to install them on their old throne. You will also gain a Casus Belli to retrieve them.

The player may also be given the option to accept disinherited Heirs (and other leaders, because you do need my Civil Wars mod for these features) from other countries into their empire, if the situation occurs.

This can even happen if you change your government type away from Imperial (or any other modded government that uses Heirs, like my Private Corporate authority in More Authorities). From the Heir's perspective, what's the difference?

- Chinese translation by Del. Thank you!

- German translation by Lucanoria. Thank you!

- Should be compatible with everything, as it alters no vanilla files. It will also be compatible with any additional modded government authority that uses heirs.
