As near as I can tell from reading the Store Copy of the new 8th edition rule book, Tomb Kings are going to need some kind of FAQ to let us know how to properly execute the Tomb King magic phase.
Tomb Kings do not generate "power dice" so there is no generation die role. So no dispell dice are generated. There is no mechanic/process in the rules for the other player to get his dispell dice.
Also, now that the spell caster level is added to the cast and dispell role, what do the Tomb Kings do if anything? The rules discuss the Dwarfs and how thier dispell attempts are modified, but nothing on the Tomb Kings.
Also also, I think the Tomb Kings spells are going to be alot easier to dispell if thier are no additions to the Tomb King casting and the opponant can add thier caster levels to the dispell attempt.
Sad Face.
I think the new changes are going to be a good thing over all; even the magic phase changes. Looking forward to playing with the new rules. Our local game store is hosting a role-out special event on the 10th. Should be fun.






Be at peace, my friend.
