Sounds good, but I'd like to suggest some changes in two major blocks: increase opinion punishment and add discounts.

More vassal opinion loss for larger domains and realms. Domain size (excluding baronies) would be the main variable.

Perhaps make it last longer too.

Discounts would be applied when disinheriting characters with the following traits/conditions:

1. Minimal to small discount for negative intelligence traits, scaling on trait severity.
2. Medium discount for disputed heritage characters.
3. Big discount for characters who have been exposed as plotters against dynasty members.
4. Big discount for known incestuous characters.
5. Free for characters that have been exposed for leading or supporting plots against you.
6. Free for rebellious dynastic vassals.

They would all incur the normal opinion penalties with the disinherited character, but 0 vassal or general opinion loss.

Nice

The devs also said theyre going to crush this meta. This'll do until then. I always get tempted to abuse disinheritance.
