Necromantic Alchemist

You have harnessed your alchemical skills and leveraged them in your ghost-hunting efforts. You gain the following benefits:

• Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
• You gain proficiency with alchemist’s supplies.
• You can use your alchemist’s supplies to produce arcane smoke that identifies invisible spirits or other creatures. You can spend one minute using your alchemist’s supplies to create a 20-foot cube of thin gray smoke centered on your tools. Any creatures or objects within the cube cannot benefit from being invisible. Once you use your alchemist’s supplies in this way, you cannot do so again until you have completed a short or long rest.
• Using your alchemist’s supplies, you can investigate a non-magical object that was owned or handled by a spirit during its lifetime. You can spend one minute using your alchemist’s supplies to glean useful information from the object. After the minute is complete, you can ask five questions that can be answered with a yes or no. The object will vibrate, glow, spin, or float in a way that makes the answer to the question clear. The object can only answer questions related to the spirit of its former   It will not respond to questions that are beyond its knowledge.
