You have formed a pact with the Arcarum Beast known as The Tower, granting you the following benefits:

• Increase your Strength score by 1, to a maximum of 20.
• You learn the Earth Tremor spell. You can cast it without expending a spell slot. Once you cast it this way, you can’t cast it this way again until you finish a long rest. You can also cast it using spell slots you have of the appropriate level. Its spellcasting ability is Strength.
• Whenever you score a critical hit, or a critical hit is scored against you, you can deal force damage equal to twice your proficiency bonus to the target and each creature within 5 feet of it. You ignore damage this feat would deal to you.
