There are other ways of accomplishing these same feats.

For example, there exists prerequisites for certain skills in order for them to show up. Edit the abilities PathOfTheMage and add pre-requisites that you will make later. Basically grants the YouCanBeAMageAbility. Then give these new Abilties to the sovereigns you wish for them to pick from... For example Markin could very well choose PathOfTheDefender, but Warrior Makes sense. Similar to Ceresa, she doesn't have to be a Mage, she could be an administrator.

What you did was ensure that the AI gets to have 2 paths at level 4 (haven't checked that, but that is what the code suggests would happen).

Of course cusom sovereigns would have to be given these Abilities otherwise you won't be able to choose these items.

The other option is to use the Prerequisite <Type>RestrictedAbilityBonusOption</Type> This will restrict certain things if a character has the particular ability, then you wouldn't have to hassle adding abilities to the custom made sovereigns. (I just don't remember if that tag works in the level up skills or not).

Ended up hardcoding the paths for all sovereigns. Worked out pretty well: the sovereigns had their logical path from day one, then at level 4 they chose an extra path, which was okay. As a nice sideffect, it made all sovereigns more viable right out of the box (Ceresa and Magnar being actually able to kill stuff with their spells, Verga trashing everything in melee, Markin being a tough nut to crack), and since everyone got it, nobody was left underpowered.

He is talking about FE not LH.

I seriously wish we could make a bunch of different personality traits that aren't seen that define which traits get picked by the Sov.  Basically a chosen path of traits for the sov that can be adjusted through making all the different AI values go up by 1 for each trait within that path.  Once all the values for that personality are full then it will just start filling in from the top down since the higher ranked skills that are counlocked through adjoining skills will have a higher base AI value.
