Power of the Behir

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

• Increase your Strength, Dexterity, or Constitution by 1, to a maximum of 20.
• You gain proficiency in Stealth.
• Your speed increases by 10 feet, and you gain a climbing speed equal to your walking speed.
• You gain resistance to lightning damage.
• As an action, you can exhale a line of lightning that is 20 feet long and 5 feet wide. Each creature in that line must make a Dexterity saving throw (DC 8 + your proficiency bonus + your Constitution modifier), taking 6d10 lightning damage on a failed save, or half as much damage on a successful one. This damage increases by 2d10 when you reach 17th level (8d10). Once your use this feature, you can't use it again until you finish a long rest.
