Half-trolls age slightly faster than their non-Troll parent race. Due to their healing ability, it's difficult to say how long they live, as many die from complications related to mutations before reaching old age.

Although exceptions always exist, most trolls are unpredictable brutes. They tend towards the chaotic evil alignment.

Half-trolls are shorter and slighter than most of their kin, but still tower above humans. These trolls stand between 7 and 9 feet tall, and can weigh approximately 300 to 400 pounds. Your size is Medium.

Your base walking speed is 30 feet.

You have advantage on Wisdom (Perception) checks that rely on smell.

As a bonus action, you can spend one Hit Die to heal yourself. Roll the die and regain a number of hit points equal to the total. If a 1 is rolled, you develop a mutation by rolling on the Mutation Table. You cannot use this ability if you have taken fire or acid damage since the end of your last turn.

Whenever you complete a long rest you regain all Hit Dice.
