Immovable

You learn to become as rigid and unmovable as a mountain. You gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You have advantage on saving throws and ability checks made against being moved against your will.
• Enemies have disadvantage on attack rolls and ability checks made to move only you.
• If you are forcibly moved against your will, you can choose to move at half speed as if you were in difficult terrain.
