         "TraitDescriptionHaunt": "A hazard with this trait is a spiritual echo, often of someone with a tragic death. Putting a haunt to rest often involves resolving the haunt's unfinished business. A haunt that hasn't been properly put to rest always returns after a time.",

+        "TraitDescriptionHex": "A hex is a spell caused by your patron's direct attention and intervention. Your patron does not take well to being disturbed repeatedly, so you can cast only one spell that has the hex trait each turn; attempts to use a second automatically fail and usually cause your familiar to hiss in displeasure as your patron rejects your call.",
         "TraitDescriptionHindering": "This armor is so heavy and bulky it slows you down no matter what. You take a -5 penalty to all your Speeds (to a minimum of a 5-foot Speed). This is separate from and in addition to the armor's Speed penalty, and affects you even if your Strength or an ability lets you reduce or ignore the armor's Speed penalty.",

         "TraitDescriptionHoly": "Effects with the holy trait are tied to powerful magical forces of benevolence and virtue. They often have stronger effects on unholy creatures. Creatures with this trait are strongly devoted to holy causes and often have weakness to unholy. If a creature with weakness to holy uses a holy item or effect, it takes damage from its weakness.",
