Legendary Adventurer

Your renown and practice in your skills has pushed you to legendary status. You have toiled to the point of near self-destruction to earn the right to have your story told for generations to come. Your hard towards to going beyond the limits of the ordinary changes you in the following ways:

• Your highest or second highest ability score (if multiple are, pick one) is reduced by 1.
• You gain a legendary action, an action that you take on the end of another creature's turn. This legendary action can only be used one time, and you regain your spent legendary action on your turn.
• You choose what you can use your legendary action for on the completion of a long rest. You can choose from any action you can perform as long as it isn't the Attack action, does not result in the casting of a spell, and doesn't modify your movement. You may also choose to be able to cast any cantrips you have learned, or to prepare a specific spell that you can cast between 1st level and 3rd level with a casting time of 1 action. You may also choose to take the option to move up to half your speed as use for your legendary action.

You can take this feat up to 3 times, and when you do, you can also choose to take the Attack action at the cost of 2 legendary actions as a use for your legendary actions. On top of that, your options for spellcasting expands; you may prepare a use for your legendary actions to be a spell that is between 4th level and 7th level that costs 2 legendary actions to use.
