race features:
Size. Roaches are small creatures and are only about 3 to
4 feet tall.
Superior Darkvision. Roaches mainly dwell in dark
tunnels deep in the earth. You have superior vision in dark
and dim conditions. You can see in dim light within 120 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.
Sunlight Sensitivity. You have disadvantage on attack rolls
and on Wisdom (Perception) checks that rely on sight when
you, the target of your attack, or whatever you are trying to
perceive is in direct sunlight.
Keen Survivors. Roaches are resilient and have an innate
knack for crafting tools to aid them. You gain proficiency in
the Wisdom (Survival) skill. Additionally, you gain proficiency
with Tinker's tools.
Relentless Endurance. When you are reduced to 0 hit
points but not killed outright, you can drop to 1 hit point
instead. You can't use this feature again until you finish a long
rest.
Mechanic Augments. Parts of your body have been
replaced with metallic augments and crude machinery. You
choose one augment at 1st level. You gain an additional effect
at 5th level, depending on which augment you chose.
At 1st level, choose one of the following options:
Mechanic Gliders. When you fall and aren’t incapacitated,
you can subtract up to 100 feet from the fall when calculating
falling damage, and you can move up to 2 feet horizontally for
every 1 foot you descend.
At 5th level: You gain back boosters that allow you to get
into the air. You gain a flying speed of 30 feet. To use this
speed, you can’t be wearing medium or heavy armor.
Metallic Chitin. When you aren't wearing armor, your AC is
13 + your Dexterity modifier. You can use your natural armor
to determine your AC if the armor you wear would leave you
with a lower AC. A shield's benefits apply as normal while you
use your natural armor.
At 5th level: You gain resistance to acid and poison
damage.
Respirator. This augment grants you the effects of the water
breathing spell once per long rest for 1 hour.
At 5th level: You can breathe normally in any environment.
You have advantage on Saving Throws made against harmful
gases and vapors (effects like cloudkill and stinking cloud,
inhaled Poisons, and the breath Weapons of some dragons)
