My goal for my last few dwarf warbands has been to make one of them a spellcaster (runesmith). Either through playing the Great Library scenario (where books scattered in the area may give you an academic skill) or by getting resource hunter with a few heroes and then try to roll 2 2 2 2 2 in exploration, to get access to academic skills. I would then pick the Arcane Lore skill, try to get a Tome of Magic to get a spellcaster.
Yes, I know it's quite hard to achieve but like I said, I've been trying with a few warbands (as opposed to a few games).
I don't much like the idea of having a Lesser Magic Dwarf spellcaster (considering dwarves' thoughts on magic). We already allow any warband to make an additional spellcaster of their own kind (for example, a Skaven Assassin Adept with arcane lore and a tome of magic may use the Magic of the Horned Rat rather than Lesser Magic if he opts to), so I don't think my gaming group would be very opposed to the idea of letting my dwarves have their on spell list if I presented something not too overpowered. As far as I understand (I've never played WFB) Dwarf Runes could be something similar to magic. Has anyone written a list for Mordheim? If not, do you have any tips on what runes could be like in Mordheim?
