Privileged Forms

1st-Level Druid, Circle of the Noble Beast Feature

The rites of your circle grant you the ability to transform into more dangerous beast forms. Starting at 1st level, you can use your Wild Shape to transform into a beast with a challenge rating as high as 1 (you ignore the Max. CR column of the Beast Shapes table). And due to your royal upbringing, you do not abide by the flight and swimming restrictions of most druids.
Starting at 4th level, you can transform into a beast with a challenge rating as high as your druid level
