Mages vs. Mountain Clans

Last time, I started as a machinist, but on the first day, I took the weapon skill. Chaos with Lightning is very effective during leveling, and Deep Freeze is good in the late game (especially against Dwarves with their high defense). I take Darkness to cast mass slow, weakness (if the opponent has a lot of attack or the hero has retaliatory strike), and to use enslave on Titans and vampirism on my own units; it looks good overall. I also take attack skills (Cold Steel, Battle Fury, and Ranged Attack; there's not much point in tactics because the Dwarf will have 100% accuracy), defense skills (Resistances is a must, the rest depends on luck), and magic skills.
