Lesser Arcanum

Prerequisite

7th level, Pact of the Tome feature

Description

When you choose this invocation, you choose a spell of 1st or 2nd level from your patron's Expanded Spells. Whenever you gain a level in this class, you can change your choice of spell.
You can cast this arcanum spell at 2nd level once without expending a spell slot, even if you haven't learned it. You regain the ability to do so when you finish a long rest.
