So, in the best lizardman lists there are usually a scar vet that has a jag charm, this gives him a bound spell of steed of shadows at power level 5, then you give him a great weapon and, wa-la. I'm thinking of trying it with an exalted here by giving him the book of secrets and taking the first spell in the lore of shadows, then give him a great weapon and maybe a battle standard (probably not), the idea is that he can hunt lone characters/warmachines/chariots because of his lovely S7.
So, what do you think, thanks for reading,
Jacob.
