====The Dreaded Thirteenth Spell (25+)====

Roll up your sleeves and eat some Warp Tokens 'cause if you pull this off you WILL have a trollface as big as a [[pauldron]] whilst your opponent rage-quits. Select a unit... no, not the small group of Swordsmen, pick that unit of Warriors of Chaos, that unit of White Lions looks good too... Much better. Now roll 4D6... 12. Before your opponent can sneer that your roll was below average, 12 of his soldiers are dead, just like that. Wait, that was a small unit and there's no survivors? Now all of them are Clan Rats instead, and you control them. This does include special characters, so you can just unleash your trollface when Teclis suddenly grows a twitchy nose and tail.
There is a reason the spell stands alone. It's game breaking and Grey <s>Knights</s> Seers can elect to take it standard. Only use against opponents you don't mind never fighting again.
