Mercenary Cost have been reduced by roughly 33%, this will make them much more viable to hire.

Raiding kicked in the teeth, since it incredibly powerful. Attrition while raiding has been doubled, because distracted soldiers are easier to kill.

Artifacts now decay half as fast when not being used, and decay 50% faster when being used.

Players are now invited to activities somewhat earlier than other characters, making it more likely you can attend.

A lot of prowess changes to traits, notably a boost to blademaster and more severe illnesses hitting a bit harder. Also don't fight while pregnant, it's just not wise.

Compatibility update.

Slight change to scheme resistance based on highest owned title.

Altered AI faction logic, making vassals less willing to sabotage themselves constantly.

Minor bugfix.

-Made sinful traits inflict -15 opinion.
-Sinful traits inflict an additional -10 to clergy opinion.
-Being a known non-believer also upsets the clergy, not just your vassals.
-Changed base skill offset to 16. This means diplomacy will provide penalties under 16 and bonuses only thereafter. Stewardship and Martial have been adjusted to make sure they are not punishing using the new offset.
-Calling allies in wars requires prestige, allies called into wars get prestige just for being called.
-Disinheriting is now more expensive, the vassal opinion penalty lasts longer, and the prestige cost is more significant. It is also stressful, and especially stressful if you are Just, Compassionate, or Forgiving.
-Many downsides of Disinheriting are reduced when disinheriting a child who has known disputed heritage, or known as a kinslayer. Because yeah, vassals aren't entirely unreasonable.
-Designating heirs costs twice the prestige, because it's insanely good anyway.
-Realm Priests are harder to ensnare in social schemes.
-Having a higher rank than your target in a seduce scheme is less of a factor.

-Huge changes to the basic opinion modifiers of opposing traits
-Sway has been nerfed to only improve relations by +50 maximum
-Allied vassals can be called into defensive wars, providing significant advantages to many small defending nations. (They can also help put down rebellions, but may be more reluctant to answer such calls to fight their own peers.)
-Prestige has been fundamentally nerfed, only for owners of T&T. Event based prestige gained has been halved. Prestige is also used more frequently, such as being necessary for recruiting guests to your court and fabricating claims.

Now also will function without More Game Rules.

...the mod is now actually fully compatible with More Game Rules. Because we all know that load order means nothing and what is important is how many 'z's you add to the file name. Bloody paradox modding systems...
