Looks like a interesting mod, I was looking into having a few more generals for the rebels to make them more challenging..
There is a really cool character trait that is relatively unknown, even though I haven't dug through this forum to see if anyone is using it: BodyguardSize
It lets you selectively increase the bodyguard size of generals and family members, any faction, as a reward for success in battle, destroying a faction, etc..
Your mod would make a good testbed, it's best if used sparingly; makes it that much more "special"..
I think at most you can double the size of the EDU #, plus maybe a few extra, the values used are percentages (1-100) , but not sure, if I use a very high value (like 1500) it will double the bodyguard.
Example:
Level Legendary_Commander
Description Legendary_Commander_desc
EffectsDescription Legendary_Commander_effects_desc
GainMessage Legendary_Commander_gain_desc
Epithet Legendary_Commander_epithet_desc
Threshold 32
Effect Command 5
Effect Authority 2
Effect MovementPoints 5
Effect LineOfSight 5
Effect BodyGuardSize 100(?) Chance 100
It also may be functional as both Effect and Affects, needs some experimenting.
Ever heard of this?
