While a Frogfolk's nature makes them far more agile and their venom makes them adapted to harsher conditions, their dependency on these does mean they fall short in other areas. You gain a +2 to Dexterity, a +1 to Constitution, and a -2 to Strength.

Accustomed to the murky conditions of the swamps they call home, Frogfolk have become excellent at seeing in dim and dark conditions. You gain Darkvision out to a range of 120 feet. You can see in dim light as if it were bright light, and darkness as if it were dim light. You can't discern color in darkness, only shades of grey.

Frogfolk can use their unique body makeup to jump farther than most creatures can. You gain a standing high jump of 15 feet, and a standing long jump of 30 feet.

A Frogfolk can use its tongue to grapple another creature, dealing damage and potentially poisoning them. As an action, you can make a melee attack against a creature within 10 feet. On a successful hit, the target takes 2d4 bludgeoning damage must succeed on a DC 12 Strength saving throw or be grappled. While grappled, the target is poisoned, and additionally takes 1d6 poison damage. You can only grapple one creature this way at a time, and you cannot attack another creature if you have one grappled. Because you are using your tongue, this attack is made with Dexterity rather than Strength. This effect ends when the grapple ends. This damage increases by 1d4 and 1d6 for each part respectively at 5th level (3d4 bludgeoning and 2d6 poison), 11th level (4d4 bludgeoning and 3d6 poison), and 17th level (5d4 bludgeoning and 4d6 poison).

Alternatively, you can use your tongue to access or pick up any unsecured objects within 10 feet that you can see and have a direct line to. Due to the additional effort needed for using a tongue as opposed to hands, this requires a bonus action rather than an object interaction. You cannot use this while a creature is grappled with your tongue.

Due to constant exposure to their own venom, Frogfolk have built up a resistance to poison and its effects. You are immune to poison damage, and have advantage on Constitution saving throws against poison.

Due to your small size, you can move yourself around more easily. However, that small size also makes it harder for you to carry or wield heavier items. You gain the following effects:

• Movement: You can move through the space of any other creature on your turn (though must end your turn on your own space). 
• Agility: You have advantage on Acrobatics checks.
• Natural Defense: Due to being small and hard to hit, you gain a +2 to your AC. 
• Carrying Capacity: You have a maximum carrying capacity of 60 pounds.
• Heavy and Two-Handed: You are unable to use weapons with the heavy or two-handed properties, including the two-handed version of versatile weapons. You cannot wear heavy armor. Additionally, you have disadvantage on attack rolls if wielding two weapons, or one weapon and a shield. If both weapons have the light property, this does not apply, and you can attack normally.

You can speak, read, and write Common.
