If you want it to be a non-ability, it has to be a score of Ø, not of 0. A score of 0 means an ability at 0, which leaves it helpless (or dead for CON), a score of Ø is a nonability.
A nonability for DEX requires that STR be a nonability as well.; the only real problem is the zero for dexterity, which renders the giant imobile object....paralyzed!![]()
Obviously, that's still no excuse for such obvious errors.It was meant as a joke, pulled together in less than 5 minutes by copy-pasta-ing the stat-block from an Animated Object
