Greater Firbolg Magic

You have grown more in touch with your innate magical abilities.  You learn the Speak With Animals spell and can cast it at will, without expending a spell slot.  You also learn Detect Magic, Disguise Self, Locate Animals and Plants, and Animal Friendship, each of which you can cast once without expending a spell slot.  You regain the ability to cast these spells in this way when you finish a short or long rest.  Wisdom is your spellcasting ability for all of these spells.  This replaces your Firbolg Magic racial trait.
