Your Intelligence, Dexterity or Strength score increases by 2, and one other ability score of your choice increases by 1.

Modrons do not age, and are effectively immortal if well maintained.

Modron generally can only be Lawful. Even rogue modrons normally see their actions as lawful, and remain lawful to some cause. However, rarely, some defective modrons have non lawful alignments.

Your size is Medium. To set your height and weight randomly, start with rolling a size modifier:

Size modifier = 2d6

Height = 5 feet + 3 inches + your size modifier in inches

Weight in pounds = 270 + (4 × your size modifier)

Your base walking speed is 30 feet.

As a result of being mostly mechanical, you gain the following benefits:

• You don’t need to eat, drink or breathe.
  [DM Optional] You do not need to eat in the same way that others do, but do need to consume an intake of modron jelly. Modron jelly is a unique form of psychomorphic energy, which has the consistency of thick jelly and emits a faint inner light. It is harvested by monodrones and stored in a large pool in Regulus. If 1 pound of modron jelly is not consumed once every 4 weeks, you will begin to degrade. Every 4 weeks that pass without consuming the Modron jelly inflicts a level of exhaustion, which does not go away with a long rest, but can be cured with magic. Otherwise, once Modron jelly is consumed, all levels of exhaustion caused by not eating are cured.
  *This rule is optional in case some campaign settings would not have this substance available.
• You are immune to disease.
• You don’t need to sleep, and magic can’t put you to sleep.

You can speak, read, and write Common and Modron. The Modron language is made up of a series of clicks, buzzes & whirs. Additionally, the dialect changes throughout the hierarchy. Modrons can only speak, read & right in a dialect of their language which can be understood by their own hierarchy, as well as the one below them, and the one above them. For example, a Quadrone can understand and speak to another Quardrone, Tridrone, or Pentadrone.

Because of your wings, you have a flying speed of 30 ft. You can’t use this flying speed if you’re wearing medium or heavy armor.

When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal.

If a modron dies, its body disintegrates into dust, leaving behind its weapons and anything else it was carrying. The energy that powers its soul returns to Mechanus to rejoin Primus' power source. You cannot be resurrected, except by a Wish spell.

You are a construct. Because you are living, you still benefit from healing magic, but resist it, meaning you only receive half the healing from a spell or potion, rounded down. Additionally, you can be healed for 1 point by the mending cantrip or by spending an action to make a DC 12 Intelligence (Tinkerer's Tools) check; a higher check may result in more healing, at the DM's discretion.

You have advantage on Intelligence (Investigation) checks made to discern illusions.

While you're not wearing armor, you have an AC of 13 + your dexterity modifier.

You have advantage on saving throws against effects that would charm or dominate you.
