Our combat lords can make huge dents in TG units, just watch out for lore of life. Flesh to Stone can make it a difficult task. Lore of death perhaps? Purple sun should take out a good few TG. In all honesty, a slann TG unit is a honey trap that really should be avoided. Lots of magic defence to weather the worst magic, take out the rest of the army.
Anyone with more experience with BK buses? Maybe some do and donts and the like. Also, what is ideal support for it? Terrorgheist/vargheists? Double varghs? Doing the mortis engine/Crypt horror centre with a bus. Would that work? Spreading my strengths a bit too thin perhaps`?
