Poison resilience: Varanix have advantage on saving throws against poison and resistance to poison damage.

Bite: Lizardfolk's fanged maw is a natural weapon, which they can use to make unarmed strikes. If they hit with it, they deal piercing damage equal to 1d6 + Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

Venomous bite: When Varanix hit with their bite attack, they can choose to force the target to make a Constitution saving throw (DC = 8 + proficiency bonus + Constitution modifier). On a failed save, the target takes 1d6 poison damage and has disadvantage on the next attack roll it makes before the end of its next turn. Varanix can use this ability a number of times equal to their proficiency bonus per long rest.

Cunning artisan: As part of a short rest, Lizardfolk can harvest bone and hide from a slain beast, construct, dragon, monstrosity, or plant creature of size Small or larger to create one of the following items: a shield, a club, a javelin, or 1d4 darts or blowgun needles. To use this trait, they need a blade, such as a dagger, or appropriate artisan's tools, such as leatherworker's tools.

Natural armor: Lizardfolk have tough, scaly skin. When they aren't wearing armor, their AC is 13 + Dexterity modifier. They can use their natural armor to determine your AC if the armor they wear would leave them with a lower AC. A shield's benefits apply as normal while they use their natural armor.

Hungry jaws: In battle, Lizardfolk can throw themselves into a vicious feeding frenzy. As a bonus action, they can make a special attack with their bite. If the attack hits, it deals its normal damage, and they gain temporary hit points (minimum of 1) equal to their Constitution modifier, and they can't use this trait again until they finish a short or long rest.

Tireless stalker: Varanix have advantage on Survival checks to track creatures that are wounded or bleeding.
