Mechana

A Mechanum is a humanoid-shaped machine. They frequently appear to be modeled after pre-existing people, but some are a smoother, more generalized shape. They are arguably constructs, although it is not certain whether they are truly "constructed" by some unknown craftsman or if they form naturally on a plane such as Mechanus. Regardless of their true origin, many appear to move less smoothly than their organic counterparts and as such may be unsettling to some and unwelcome in certain communities.

ability score increase:

Mechanic Specialization. All Mechana are specialized in a particular area, and as such, they get +3 to an ability score of your choosing.

age: Any

alignment: Some lean neutrally, but all fall into lawful, following a set of rules to some extent.

Size: Medium

speed: 30ft

Languages: Common, Machinae, and one language of your choice spoken by a creature for which you have Specialization

race features:

Precision. On any Strength, Dexterity, or Constitution based skill check, you may opt to use the result of the average roll rather than rolling the die for it. (Note: you may only apply this BEFORE you roll.)

Mechanical Accuracy. Mechana are notoriously good at running quick probability calculations. Once per long rest, a Mechanum may add their intelligience modifier to their attack roll.

Specialization. Many Mechana have specialized knowledge on a given creature type: aberration, beast, celestial, construct, dragon, elemental, fey, fiend, giant, humanoid, monstrosity, ooze, plant, or undead. Once per short rest, when they encounter a creature of their specialty, they may make a Knowledge Check to learn a specific stat of the creature. The DC for this check is set at the DM's discretion, but may be based on the rarity of the creature encountered, the character's personal experience with this particular type of creature, and the character's personal experience with this individual creature. Once Specialization has been used on a creature, the character can not use Specialization on that creature again.

1d100	Result
1-50	An ability score of the DM's choosing
51-69	An ability score of the player's choosing
70-79	The creature's hitpoint total
80-89	The creature's resistances and immunities (if applicable)
90-99	The creature's vulnerabilities (if applicable)
100	The creature's spell list (if applicable)

Simulacrum. The Mechanum is modeled to look like a member of another Medium race of your choosing. To other humanoids, Mechana fall very firmly into the Uncanny Valley, and, as a result, have disadvantage on any Charisma based skill checks against humanoid creatures. Conversely, non-humanoid creatures have difficulty distinguishing a Mechanum from a humanoid of that race and hold biases (or lack thereof) accordingly.

Retournant

Much the way Revenants claw their way to vengeance, Retournants have a grasp on unlife (albeit a tenous one) that allows them to seek revenge. Retournants tend to be single-minded, but can usually cooperate with others if it forwards their own purposes. Despite their drive for justice in their minds, they typically remember little about their life.

ability score increase: +2 Strength, +1 Constitution, +1 Charisma

age: Any. Retournants can form from both old deaths and young deaths.

alignment: Usually chaotic

Size: Medium

speed: 30ft

Languages: Common and one language of your choice

race features:

Undead. Being a form of undead, you are immune to poison damage and to being poisoned. You are also resistant to necrotic damage.

Vengeful Willpower. Your drive for revenge renders you nigh fearless. You have advantage against being frightened.

Darkvision. You have darkvision for 60ft.

Rest is for the dead. Once per long rest, you can use a bonus action to remove a level of exhaustion.
