Ironskin give immunity to the effects of (among other things) sorcery. Does this mean that an attacker can not use the sorcery ability to generate the needed range to hit the target or just that the target with ironskin is immune to any damage added via sorcery?
For instance, say you have sorcery 2 and are 5 spaces away from a target with Ironskin. If you roll 3 range can you use the sorcery to add 2 and thus hit or do you come up short?
