I am not aware whether this is a case just for undead companions or for all companions in general. As enjoy playing Sylvania too much so far, culture of Vampire Lords remains my only appropriate reference point.

Too high levels?
At least from my experience playing with Sylvania, I found that Wight Knights companions starting with level 24 seem very hard to level up.

Vampires do level up more easily due to magic and the fact that they start at level 21 (by the time they reach level 24 while spamming magic, wight knights remain at level 24).

Because undead companions start with neither points allocated in leadership nor tactics, I doubt they would prove to be good party leaders/lords, as they would have very few points to allocate left.

Consequently, my existing impression with companions is that they serve as jacks-of-all-trades in terms of fighting skills and that's the end of the story.

Question for players:
Has anyone found that companions can level up to become good material for party leaders eventually? Do companions start at lower levels for other cultures and do they have more diversified skill sets?

For developers:
Are there any plans to eventually have recruitable companions with lower levels to ensure that their development can be more customized?

I understand that having a bunch of vampires with spellcasting around 200 in your party would quite disrupt game balance with the way magic works now.

So I totally understand why vampires starting at level 10, equippable with heavy armor and having huge magic development potential would crash the experience.

However, I would expect Wight Knights without access to magic to be more customizable.

Massive thank you for buidling amazing mod that actually convinced me to play Bannerlord instead of going back again to Warband!
