- Trolls can choose a new class (Smasher) - thanks to Esme for the idea

- Eagles and other birds, while they can still hold items in their talons, can
  no longer use them effectively as weapons

- Victims of a failed incantation, for example a 'sleep' spell, can realize
  more easily that the failed spell was targeted at them
