Thesis Spell (Charisma)

You dedicate yourself to perfecting a single spell. Choose one spell you can cast of 2nd level or lower to be your thesis spell:

• You gain a bonus to your thesis spell’s Attack roll or spell save DC equal to half your proficiency bonus (rounded down).
• You can cast your thesis spell at its lowest level without expending a spell slot once per long rest.
• Once per long rest when you cast your thesis spell, you can roll your spell attack at advantage, or cause a creature to roll their saving throw at disadvantage.
• You always recognize a casting of your thesis spell so long as you have the necessary senses to do so.
