What is This Used For "Splinter of Darkness"

[tiberiu]

What? You can't buy undead? So no more Stone Skin and Target on Cursed Ghost for me I guess.

You have to admit it would be a little weird for Olaf to go around trying to extinguish the Undead with an Undead army. It must be story related... but I will miss my ghosts and my vampires . On the bright side, all undead units except zombies and melee skeletons are overpowered so this will help create a harder challange.
