Ghouls and Radiation Storms: A Ghoul’s immunity to radiation creates an interesting party dynamic during a Radiation Storm. The Ghoul can continue traveling safely while the rest of the party must shelter or suffer. This may lead to split-party scenarios where the Ghoul scouts ahead while the others wait out the storm.
