Origin Feat
You gain the following benefits.
Lengthened Stride. Your Speed increases by 5 feet.
Resilient Anatomy. You have Advantage on saving throws against effects that would compel you to shape-shift against your will.
Additionally, when you fail a Constitution saving throw, you can take a Reaction to roll 1d4 and add the number rolled to the save, potentially turning the failure into a success. You can use this benefit a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
