Your trickster spirit and fey nature manifests itself in a variety of ways.

Ability Score Increase. Your Intelligence or Wisdom score increases by 2, and your Dexterity score increases by 1.

Age. Leprechauns come of age at around 20. Their aging process then slows down to one more akin to their fey brethren, and many end up living for hundreds or even thousands of years.

Alignment. Leprechauns tend towards chaotic alignments. Those that remain in the Feywild tend to become more neutral, while those that live further into the Material Plane generally end up leaning towards good or evil depending on what they encounter.

Size. Leprechauns average at about two to three feet tall. Your size is Small.

Speed. Your base walking speed is 30 feet.

Faerie Kin. You were born infused with the magic of the fey. You have two creature types: humanoid and fey. You can be affected by a spell or ability if it works on either of your creature types.

Additionally, you have advantage on saving throws against being charmed, and magic can’t put you to sleep.

Gold Gatherer. You have learnt the techniques behind gathering small scrapings of gold and forging them into gold coins. During a short or long rest, make a Dexterity (Sleight of Hand) check and divide that result by 5 (rounded down), provided you have been in an urban area for a fairly large amount of time since your last rest. Provided you have access to at least one set of artisan's tools, you can forge that many gold pieces as part of the short rest, or twice as many as part of the long rest.

Additionally, you add half your proficiency bonus (rounded down) to any check involving money or gold. If you would already add your proficiency bonus to the check, you can add the additional half.

Cobbler of the Fair Folk. You have proficiency in cobbler's tools, and double your proficiency bonus in them when you use them to create or adapt a shoe.

When you use cobbler's tools to make a shoe, you may as an action magically resize the shoe to perfectly fit any humanoid or fey of Medium size or smaller you choose. Once you have done so, you may not resize the same shoe again.

Leprechaun Magic. You know the minor illusion cantrip. When you reach 3rd level, you can cast the color spray spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the Jim's glowing coin spell once with this trait and regain the ability to do so when you finish a long rest. Choose Intelligence, Wisdom or Charisma as your spellcasting ability for these spells.

Lucky. When you roll a 1 on the d20 for an attack roll, ability check, or saving throw, you can reroll the die and must use the new roll.

Languages. You can speak, read, and write Common and Sylvan.
