Troll Power

You have developed traits similar to that of a troll, granting you the following benefits:

• Increase your Strength or Constitution by 1, to a maximum of 20.
• You have advantage on Wisdom (Perception) checks that rely on smell.
• At the start of your turn, you can regain a number of hit points equal to your proficiency bonus, if you haven't taken acid or fire damage since the start of your last turn. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
