Brute Lizardfolk

Hold Breath. The lizardfolk can hold its breath for 15 minutes.

Reckless attack. When the brute makes an attack it can decide to attack recklessly. Doing so gives it advantage on melee weapon attack rolls using strength during this turn, but attack rolls against the brute have advantage until the start of its next turn.

Hungry Jaws. As a bonus action, the brute can make a special attack with its bite. If the attack hits, it deals its normal damage, and the brute gains 4 temporary hit points. Once the brute uses this special attack it can't use it again until it finishes a short or long rest.
