Giantborn

The blood of the first orcs, giants among mortals, flows through your veins, granting you the following benefits:

• Increase your Strength score by 1 to a maximum of 20.
• Immediately after you use your Relentless Endurance trait, you can spend a number of Hit Dice up to half your level to heal yourself. Roll the dice, add your Constitution modifier to each roll, and regain a number of hit points equal to the total (minimum of 1). For the next ten minutes, your size is increased by one category — from Medium to Large, for example. While enlarged, you have advantage on Strength checks and Strength saving throws, and your attacks deal 1d4 extra damage.
