Grung Parentage

Grungs are froglike Humanoids adapted to life in rainforests and tropical jungles. Their ancestors lived in trees and shade, which explains much about their physiology.
Grungs are amphibians and live the first phase of their lives as tadpoles. A grung hatchery is usually a ground-level pool. About three months after hatching, a grung tadpole takes on the shape of an adult. It takes another six to nine months for a grung juvenile to reach maturity.
All grungs are a dull greenish gray when they are born, but each individual takes on a new color as it grows to adulthood: red, orange, green, blue, or purple. Color doesn't appear to be inherited from birth parents but has to do with the environment.
Grungs secrete a substance that is harmless to them but poisonous to other creatures. A grung can also use their venom to poison their weapons.

Grung Traits

You have a pool of 16 points to spend between your two birth parents. If either or both of your birth parents are grungs, choose from the following.

Amphibious (1 Point)

• You can breathe air and water.

Climb (3 Points)

• You have a climbing speed of 25 feet.

Little (–2 Points)

• Your base speed reduces to 25 feet. In addition, if you inherit this trait from your other birth parent also, your size is Small.

Poison Dart (6 Points)

• As an action, you can apply the poison of your skin to any piercing weapon. On a hit, the target must succeed on a DC 12 Constitution saving throw or take 2d4 poison damage.

Poisonous Skin (12 Points)

• Any creature that grapples you or otherwise comes into direct contact with your skin must succeed on a DC 12 Constitution saving throw or become poisoned for 1 minute. A poisoned creature no longer in direct contact with you can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Other grung are immune to this trait.

Water Dependency (–3 Points) If you fail to immerse yourself in water for at least 1 hour during a day, you suffer one level of exhaustion at the end of that day. You can only recover from this exhaustion through magic or by immersing yourself in water for at least 1 hour.
