Primordial Blessing of Water

You have received a boon from the Elemental Plane of Water, perhaps from a Water Elemental or a Marid. You gain the following benefits:

• Increase one ability score by 1, to a maximum of 20.
• Your armor class increases by +1.
• You learn the freedom of movement spell. You can cast this spell once without expending a spell slot. Once you do so, you can’t cast the spell in this way again until you finish a long rest. You can also cast this spell using spell slots you have of the appropriate level.
