The Beard

Restriction: No Beard, No Good

You must have a beard to hope to draw the attention of the Beard. Typically elves and half-elves lack the facial fortitude to gain favor with the Beard.

Basically a Wizard

As all wizards have beards, starting at 1st level, when your Pact Magic feature lets you learn or replace a warlock cantrip or a warlock spell of 1st level or higher, you can choose the new spell from the warlock spell list or the wizard spell list. You must otherwise obey all the restrictions for selecting the spell, and it becomes a warlock spell for you.

Majestic Beard

Starting at 1st level, a magnificent magical beard appears on your face, which is the source of your magic. You can use it as a spellcasting focus for your warlock spells. While you have your magical beard, you have advantage on Charisma checks against other intelligent creatures that have a beard, such as dwarves or bearded devils.

Your magical beard vanishes when you have no warlock spell slots remaining, and reappears whenever you finish a short or long rest or regain one or more warlock spell slots by some other means. Whenever your magical beard vanishes, it is replaced by your original beard until it reappears.

Invoke Beard

Starting at 6th level, you can stroke your beard as a bonus action to regain one expended warlock spell slot. Once you regain a spell slot in this way, you can't do so again until you finish a long rest.

Iron Curtain

Beginning at 10th level, your magical beard counts as a shield you are wielding and are proficient with, increasing your AC by 2 while you have it. You can still only benefit from one shield at a time.

Uncowed, Unkempt, Unshaven

Beginning at 14th level, while you have your magical beard, you can't die due to failing death saving throws, and massive damage or other effects can't cause you to die instantly.
