Giant's Blood

You awaken the latent giant's blood flowing through your veins, granting you the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• You can cast the enlarge/reduce spell on yourself, using only the spell's enlarge option and requiring no spell slot or components, and you must finish a long rest before you can cast it this way again. Your spellcasting ability for the spell is intelligence.
