Absolute skills

You need to evaluate not only the super ability itself but also the path leading to it. For example, the super ability of the Dwarves is significantly weakened by the fact that it requires summoning and chaos magic. While chaos magic can be taken for a Dwarf, even though I would prefer light, summoning is definitely not needed for a Dwarf. The magic-based super ability is spoiled by machines, which are as useful to a mage as a saddle is to a cow. But a Necromancer has it good; all the skills leading to "Howl of Terror" are useful to him. My choice is "Call of Urgash" and "Pure Rage".
