Well, I actually made a speech to troops at one point, so leadership likely was involved. Promised them some benefits after the camp attacks to increase the morale- if Osokans weren`t so ugly I could have also motivated them with permisson to have free way with the females in the city.
Actually, has any side met female Osokans at all?
So he has no Leadership skill but Warfare? Commisar has the opposite situation, which is a bit weird since he actually a naval officer. I don`t want to roleplay him as someone completely ignorant with military matters.
Edit- Galahad has Leadership skill. It is a bit diffrent than providing battlefield bonus, though.
So far only Coll, and on Osokan side this mysterious Vasilisk and Drakkon provide bonuses in strategy.
