Sorcerous Origin: Under the Redcap

There must always be a Redcap. When the previous one died, you have been chosen to assume it's mantle. This magical hood is prophecized to lead the goblinoid races to greatness. It has always been worn by goblinoid leaders, but it is unclear how it chooses it's next wielder when the current one dies.

Donning the Mantle

At 1st level, you gain the ability to cast Mage Armor once without using spell slots. Furthermore, when casting Mage Armor with this feature, you can apply one Metamagic option that you have access to freely, without using sorcery points. You regain the use of this feature when you take a long rest.

Legendary Basis for a System of Government

At 1st level, your hit point maximum increases by 1 and increases by 1 again whenever you gain a level in this class.

If you couldn't previously, you can now speak, read, and write Goblin. Additionally, whenever you make a Charisma check when interacting with goblins, your proficiency bonus is doubled if it applies to the check.

Pure Unadulterated Goblin Luck

Starting at 6th level, when another creature you can see makes an attack roll, an ability check, or a saving throw, you can use your reaction and spend 2 sorcery points to roll 1d4 and apply the number rolled as a bonus or penalty (your choice) to the creature’s roll. You can do so after the creature rolls but before any effects of the roll occur.

Winged Friend

At 14th level, you gain the ability to summon a giant eagle to ride, gaining a flying speed equal to your current speed.

There is a magical link connecting you to your eagle, making it easy for you to ride it even if you are otherwise unable to ride beasts, and also making it extremely hard to force you to dismount against your will, effectively as hard as dismembering you.

The eagle can't take any actions, shares your HP pool and your AC. It is dismissed if you dismount. They last until you dismiss them as a bonus action on your turn.

Effectively, the eagle should be treated as a pair of wings.

The Foretold Ruler

Beginning at 18th level, you can channel the majesty of the goblinoids king of legend, causing those around you to become awestruck or frightened.

As an action, you can spend 5 sorcery points to draw on this power and exude an aura of awe or fear (your choice) to a distance of 60 feet. For 1 minute or until you lose your concentration (as if you were casting a concentration spell), each hostile creature that starts its turn in this aura must succeed on a Wisdom saving throw or be charmed (if you chose awe) or frightened (if you chose fear) until the aura ends. A creature that succeeds on this saving throw is immune to your aura for 24 hours. Other Goblinoids have disadvantage when saving against this feature.
