MISSING MODIFIERS in effects and inventory -- temporary hit points: for example the circle form of a moon druid as created by the builder updates the AC but not HP. you can manually correct the maximum hit point but not the temporary ones -- proficiency: as per ioun stone of mastery -- negative HP maximum modifier to diminish hit points (for undead effect for example) a -10 is parsed as NaN (not a number?) NON-ACCESSIBLE MODIFIERS in effects and inventory -- Speed: cloak of the manta ray provides a base speed swimming but it cannot be chosen in a custom item -- generic saving throw modifier (cloak of protection)
