I recently picked up a Karman army and have been having a ton of fun with Guru Lucius leading a unit of 4 Kaptars. Lucius gives the unit he is leading stealth when they are in cover and given the take cover drill. This gives the usually fragile kaptars a lot more room to step out and fire all their weapons. The other benefit is that Lucius comes with 2 drum guns listed separately on his profile. This gives his unit the possibility of firing at 3 different targets with the split fire combat drill. This is extremely helpful when dealing with a UNA morningstar list as they are able to field a large number of smaller sized infantry units and if you’re lucky they’ll have left the triple lens helmets at home.

I am not totally sold on using diamond over a king buggy though. The flamers seem to be much more useful at clearing out infantry and for AFV killing, nothing beats the jungle buggy. Then again I usually run a Nova list so having a hero in an afv seems like a bit of a waste if they are anything less than a Saint.
