Sorcery versus Ironskin
Sorcery may not add damage to any attack that includes a figure with Ironskin. It may add range to the attack, but not Sorcery. Yes, Laurel can get around this. The damage immunity granted by Ironskin does extend to all figures affected by an attack that includes a model with Ironskin.
