Druid Wild Shape

When creating a druid, the following is the rule for handling the Wild Shape:


 * The druid is able to change into the shapes of as many forms as equal to their spell casting modifier. The animals must be selected based on the druid's selected Circle. You can ask the DM for advice and approval if you wish to alter the initial types.
 * Over the course of a week's worth of long rests, they can learn more wild shapes by observing the animal and their habits. Then they must pass a Nature (INT) and Arcana (INT) checks to achieve the form. The DC is set by the DM based on the type of creature they are observing.
