Bulette's Might

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

• Increase your Strength or Constitution by 1, to a maximum of 20.
• You gain a burrowing speed equal to your walking speed.
• You gain tremorsense out to a range of 60 feet.
• If you burrow at least 15 feet, then immediately hit a creature that isn't underground with a melee attack, you can force the creature to succeed on a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier) or be knocked prone.
