This patch changes the 'Inverse' skill to 'Nature', which chooses a spell randomly from a table of sixteen spells. Hopefully this can become its own custom skill in the future for one or more of the guest characters - we wanted to replace Revert with this, since it does absolutely nothing anymore other than changing the Morphed character back to normal, but it was too convoluted due to other Morph-related patches... so then we decided instead to use another pre-existing skill and have it change to Nature depending on character ID, but unfortunately it was too time-consuming for our busy-with-RL coder.
