I had my thousand sons lead by a Sorcerer. I rolled a 5 for his divination power and he was able to get the power that let's him reroll everything. In close combat, his squad charged a squad of 20 boyz. The sorcerer was in the front. After all my blows were struck, there were still 19 boyz left over, and they did 11 wounds. I rolled the wounds 3 at a time against my sorcerer, and since he was able to reroll them, he failed none. In subsequent turns he failed one save, but I LookOutSir'd it to a Thousand Son.
Is this right? Can a single sorcerer placed at the front of a squad make his squad bullet proof?
