Master of Mimicry

You have learned to temporarily mimic even the training of others. You gain the following benefits:

• Increase your Dexterity or Wisdom score by 1, to a maximum of 20.
• Whenever another creature you can see uses a skill or tool, you can use your reaction to gain proficiency in that skill or tool. Proficiencies gained in this way last for 1 hour, and you can only mimic one proficiency at a time. Once you use this ability, you can’t do so again until you finish a short or long rest.
