King's traits and attributes

[Ironside]

does the king's influence affect the prince's traits when they are conceived or when they actually come of age.

e.g. if king has influence of 3 and his wife gives birth to a sone, but then during the next 16 years gains massive influence, say 9, which influence is used to roughly determine the prince's attributes?

v&v is when coming of age, while the stats are from when the last time your king (and that can be the heirs brother) had a stat change, even an invisible one due to being too small (aka winning or losing a battle/province).

The prince's attributes are +3--4 of his "father" (in practice his king), with better rolls the higher the influence is. +3 only happens when the influence is high and the king got low stats and the opposite for -4.

Hmmm is it better to have him gain dread or gain happiness though? I remember releasing a few times giving -1 dread but +20 happiness.

They take out eachother, but the dread is inheirited, making it a better stat.
