Numbing Knowledge

A fraction of the overwhelming knowledge resting within the occult blade now lashes out at your command, you gain the following benefits:

• Increase your Charisma score by 1, to a maximum of 30.
• You learn the hypnotic pattern spell and can cast it once without expending a spell slot. You regain the ability to cast the spell in this way when you finish a long rest. Charisma is your spellcasting ability for the spell.
