Firbolg Sylvan Magic

Your connection to fey magic deepens. You learn the speak with animals spell and can cast it at will, without expending a spell slot. You also learn invisibility and speak with plants, each of which you can cast once without expending a spell slot. You regain the ability to cast these two spells in this way when you finish a short or long rest. Wisdom is your spellcasting ability for all three spells.
