Some tips regarding byzantium succession law
- Blinding and castrating completely nullifies the lineage. You cant skip your son over to grandson by doing those.
- Women can never inherit but always passes it on.
- If the succession tooltip is showing no one, the game will still try to go up and find eligible characters through other branches.
- It has elective features as well. If game fails to/ or bugs out( happened to me) to find heirs, most competent person will be chosen.
My Komnenons line for byzantium , ruled unbroken from 1377, was interrupted by a weird bug where instead of going through my ruler’s oldest aunt ( Queen of spain) into her son, it went through second oldest aunt to her circassian husband.
The circassian pretender ruled for 20 good years, with no heir apparent.
After that, the game correctly traced back the lineage to the eldest son of the previously mentioned eldest Aunt.
So thats how i got spain into pu with personal union.
( the same spain that converted orthodox from my older post)
