Chosen Spell (Druid)

2nd-level Circle of the Land druid feature

Your connection to the land is represented by your Chosen Spell. Choose one 1st level spell from your Circle Spells or the druid spell list. The Chosen Spell is always prepared for you and does not count for the number of Spells Prepared. Additionally, once per long rest, you can expend a use of your Wild Shape feature to cast the Chosen Spell, without expending a spell slot or requiring material components. The spell is cast at a level equal to half your druid level (rounded up).

Whenever you reach a level in this class that grants the Ability Score Improvement feature, you can replace your Chosen Spell with another 1st-level spell from the druid spell list or your Circle Spells.
