Was going to put the mounted guys all in with the knights. Could run them with 3 all right next to each other with the Wizard in the middle to make the other characters benefit from the white cloak effect. It has the downside of miscasts hurting more than usual but it's where I plan to start. I plan to hide the level 2 wiz in with the small archer detatchment and run the wp with the halberds of course.
For magic, my plan is to roll for spells with the level 2 and keep one of these spells: Flock of Doom, Pann's Impenetrable Pelt, Transformation of Kadon. Drop any of the better spells for the signature because I want my level 4 to get the good spells and also get double Wildform spells. With the mounted characters all in the same unit, it should turn Savage Beast bubble spell into a game winner. I don't put much stock in that Pelt spell mostly because the characters are already built pretty resiliant. Damage output would be more desired.
Thinking of dropping potion of strength for the musicians in the Demi Units but I think I'll probably try it with the potion first crack I get.
