Chaos unit recruitment ranks

[MrRip]

Hey everyone!

I'm currently trying to figure out why my Chaos units are getting recruited at such high ranks.
-The only rank-increasing tech I have is Aspiration for Greatness, which gives +2 to chaos warriors and aspiring champions. I skipped the tech which buffs marauder recruitment ranks.
-Archaon's horde has the mound of blades structure, which gives +2 to everything.
-Archaon does not have Gathering of Might skilled at all.
-Archaon has the beast tamer follower which only gives +1 to war beasts

Yet, Archaon can currently recruit marauders, chosen and knights at rank 4 and chaos warriors and warhounds at rank 6
Similarly, Sigvald is able to recruit marauders at rank 6 without any special buildings
So somehow I'm getting a +2 bonus on archaon and a +3 bonus on sigvald seemingly from nowhere.

What else effects recruitment ranks? Does horde growth or horde encampment level play a factor? Perhaps being in friendly vassal territory or areas with high chaos corruption?

Personal lord traits taken into account?

Archaon has none that should affect it. Sigvald has his starting trait of +3 on marauders, but he's recruiting at 6

Don't know the answer to your question, but i've also noticed this with both Chaos & Beastmen.

You add all the xp buffs and it's maybe 4-6, but when recruiting they're getting 9xp. Not sure if it's a bug or hidden feature

Just did some further testing by building the reliquary of chaos and checking ranks and then destroying all recruitment buildings and checking again.
the reliquary of chaos added 2 ranks, instead of the 1 it should have from replacing a +2 bonus with a +3 bonus.

after demolishing the newly built reliquary on archaon and mound of blades on sigvald, archaon's recruit ranks dropped to 0 for chosen, knights and marauders, and 2 for chaos warriors. sigvald's marauder recruit rank dropped from 9 with the mound to 6 without.

therefore it would appear that
A: Sigvald's personal trait of +3 to marauders is a typo or bugged, and is actually +6
B: the mound of blades and reliquary of chaos buildings are both either typos or bugs, as they offer double the bonuses they say they do.
