RACE
Deathless Nature: You don't need to breathe.
Spider Climb: You have a climbing speed equal to your walking speed. In addition, at 3rd level, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.
Vampiric Bite: Your fanged bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Constitution modifier, instead of your Strength modifier, to the attack and damage rolls when you attack with this bite. It deals 1d4 piercing damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite.
When you attack with this bite and hit a creature that isn’t a Construct or an Undead, you can empower yourself in one of the following ways of your choice:
You regain hit points equal to the piercing damage dealt by the bite.
You gain a bonus to the next ability check or attack roll you make; the bonus equals the piercing damage dealt by the bite.
You can empower yourself with this bite a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Background
Variant Feature: Retainers
If your character has a noble background, you may select this background feature instead of Position of Privilege.

You have the service of three retainers loyal to your family. These retainers can be attendants or messengers, and one might be a majordomo. Your retainers are commoners who can perform mundane tasks for you, but they do not fight for you, will not follow you into obviously dangerous areas (such as dungeons), and will leave if they are frequently endangered or abused.

FEATS
Poisoner
You can prepare and deliver deadly poisons, gaining the following benefits:

When you make a damage roll, you ignore resistance to poison damage.

You can coat a weapon in poison as a bonus action, instead of an action.

You gain proficiency with the poisoner's kit if you don't already have it. With one hour of work using a poisoner's kit and expending 50 gp worth of materials, you can create a number of doses of potent poison equal to your proficiency bonus. Once applied to a weapon or piece of ammunition, the poison retains its potency for 1 minute or until you hit with the weapon or ammunition. When a creature takes damage from the coated weapon or ammunition, that creature must succeed on a DC 14 Constitution saving throw or take 2d8 poison damage and become poisoned until the end of your next turn.

MONK

Martial Arts
At 1st level, your practice of martial arts gives you mastery of combat styles that use unarmed strikes and monk weapons, which are shortswords and any simple melee weapons that don't have the two-handed or heavy property.

You gain the following benefits while you are unarmed or wielding only monk weapons and you aren't wearing armor or wielding a shield:

You can use Dexterity instead of Strength for the attack and damage rolls of your unarmed strikes and monk weapons.

You can roll a (d6) in place of the normal damage of your unarmed strike or monk weapon.

When you use the Attack action with an unarmed strike or a monk weapon on your turn, you can make one unarmed strike as a bonus action. For example, if you take the Attack action and attack with a quarterstaff, you can also make an unarmed strike as a bonus action, assuming you haven't already taken a bonus action this turn

Ki
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.

Unarmored Movement
Starting at 2nd level, your speed increases by (20) feet while you are not wearing armor or wielding a shield

At 9th level, you gain the ability to move along vertical surfaces and across liquids on your turn without falling during the move.

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 point to make a ranged attack with a range of 20/60 using 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.

Ki-Fueled Attack
Also at 3rd level, if you spend 1 ki point or more as part of your action on your turn, you can make one attack with an unarmed strike or a monk weapon as a bonus action before the end of the turn

Slow Fall
Beginning at 4th level, you can use your reaction when you fall to reduce any falling damage you take by an amount equal to five times your monk level.

Quickened Healing
Also at 4th level, as an action, you can spend 2 ki points and roll a Martial Arts die. You regain a number of hit points equal to the number rolled plus your proficiency bonus.

Extra Attack
Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Stunning Strike
Starting at 5th level, you can interfere with the flow of ki in an opponent's body. When you hit another creature with a melee weapon attack, you can spend 1 ki point to attempt a stunning strike. The target must succeed on a Constitution saving throw or be stunned until the end of your next turn.

Focused Aim
Also at 5th level, when you miss with an attack roll, you can spend 1 to 3 ki points to increase your attack roll by 2 for each of these ki points you spend, potentially turning the miss into a hit.

Ki-Empowered Strikes
Starting at 6th level, your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Evasion
At 7th level, your instinctive agility lets you dodge out of the way of certain area effects, such as a blue dragon's lightning breath or a fireball spell. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

Stillness of Mind
Starting at 7th level, you can use your action to end one effect on yourself that is causing you to be charmed or frightened.

Purity of Body
At 10th level, your mastery of the ki flowing through you makes you immune to disease and poison.

MONK - WAY OF DEATH SUBCLASS
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).

Hour of Reaping
At 6th level, you gain the ability to unsettle or terrify those around you as an action, for your soul has been touched by the shadow of death. When you take this action, each creature within 30 feet of you that can see you must succeed on a Wisdom saving throw or be frightened of you until the end of your next turn.
