Naturalist

Your extensive study of nature rewards you with the following benefits:

• Increase your Intelligence score by 1, to a maximum of 20.
• You gain proficiency in the Nature skill. If you are already proficient in the skill, you add double your proficiency bonus to checks you make with it.
• You learn the druidcraft and detect poison and disease spells. You can cast detect poison and disease once without expending a spell slot, and you regain the ability to do so when you finish a long rest.
