Age. Gnomes mature at the same rate humans do, and most are expected to settle down into an adult life by around age 40. They can live 350 to almost 500 years.
Alignment. Gnomes are most often good. Those who tend toward law are sages, engineers, researchers, scholars, investigators, or inventors. Those who tend toward chaos are minstrels, tricksters, wanderers, or fanciful jewelers. Gnomes are good-hearted, and even the tricksters among them are more playful than vicious.
Size. Gnomes are between 3 and 4 feet tall and average about 40 pounds. Your size is Small.
Darkvision. Accustomed to life underground, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Gnome Cunning. You have advantage on all Intelligence, Wisdom, and Charisma saving throws against magic.
Languages. You can speak, read, and write Common and Gnomish. The Gnomish language, which uses the Dwarvish script, is renowned for its technical treatises and its catalogs of knowledge about the natural world.
Artificer's Lore. Whenever you make an Intelligence (History) check related to magic items, alchemical objects, or technological devices, you can add twice your proficiency bonus, instead of any proficiency bonus you normally apply.
Tinker. You have proficiency with artisan's tools (tinker's tools). Using those tools, you can spend 1 hour and 10 gp worth of materials to construct a Tiny clockwork device (AC 5, 1 hp). The device ceases to function after 24 hours (unless you spend 1 hour repairing it to keep the device functioning), or when you use your action to dismantle it; at that time, you can reclaim the materials used to create it. You can have up to three such devices active at a time.
When you create a device, choose one of the following options:

Clockwork Toy. This toy is a clockwork animal, monster, or person, such as a frog, mouse, bird, dragon, or soldier. When placed on the ground, the toy moves 5 feet across the ground on each of your turns in a random direction. It makes noises as appropriate to the creature it represents.
Fire Starter. The device produces a miniature flame, which you can use to light a candle, torch, or campfire. Using the device requires your action.
Music Box. When opened, this music box plays a single song at a moderate volume. The box stops playing when it reaches the song's end or when it is closed.
Unarmored Defense: While you are wearing no armor and are not wielding a shield, your AC equals 10 + Dexterity modifier + your Wisdom modifier.
Martial Arts: When unarmed or using monk weapons you can use Dexterity instead of Strength for attack and damage rolls, you can roll d4 for damage instead of normal, and when you use the Attack action you can make a strike as a bonus action. Monk weapons are shortswords and simple melee weapons that don't have the heavy or two-handed property.



Ki
Starting at 2nd level, your training allows you to harness the mystic energy of ki. Your access to this energy is represented by a number of ki points. Your monk level determines the number of points you have, as shown in the Ki Points column of the Monk table.

You can spend these points to fuel various ki features. You start knowing three such features: Flurry of Blows, Patient Defense, and Step of the Wind. You learn more ki features as you gain levels in this class.

When you spend a ki point, it is unavailable until you finish a short or long rest, at the end of which you draw all of your expended ki back into yourself. You must spend at least 30 minutes of the rest meditating to regain your ki points.

Some of your ki features require your target to make a saving throw to resist the feature's effects. The saving throw DC is calculated as follows:

Ki save DC = 8 + your proficiency bonus + your Wisdom modifier
Flurry of Blows
Immediately after you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.

Patient Defense
You can spend 1 ki point to take the Dodge action as a bonus action on your turn.

Step of the Wind
You can spend 1 ki point to take the Disengage or Dash action as a bonus action on your turn, and your jump distance is doubled for the turn.

Deflect Missiles
Starting at 3rd level, you can use your reaction to deflect or catch the missile when you are hit by a ranged weapon attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier + your monk level.

If you reduce the damage to 0, you can catch the missile if it is small enough for you to hold in one hand and you have at least one hand free. If you catch a missile in this way, you can spend 1 ki to make a ranged attack (range 20/60 feet) with the weapon or piece of ammunition you just caught, as part of the same reaction. You make this attack with proficiency, regardless of your weapon proficiencies, and the missile counts as a monk weapon for the attack.

Touch of Death
Starting when you choose this tradition at 3rd level, your study of death allows you to extract vitality from another creature as it nears its demise. When you reduce a creature within 5 feet of you to 0 hit points, you gain temporary hit points equal to your Wisdom modifier + your monk level (minimum of 1 temporary hit point).
