Ferocious is really the only worthwhile skill to even taken on skeleton warriors aside from martyr if you need one. It's pretty potent too, even at 6 dmg. 3 skeleton warriors with ferocious for a total of 76 ap can take out one full health KoL by themselves pretty effortlessly. For the ap, they are definitely a bargain. If anything, the ap could gain a point or two (or drop the prices of the other skills they have as there is never a good time to take, ie., hard-boiled on a skeleton warrior for 14ap)
And skydancer isn't the only one.. I'm 21-0-0 so far so his success is very much repeatable
