Potion rare
This potion has a red and purple layer which need to be mixed before use. After drinking this potion, either you gain proficiency in any two skills or tools of your choice or you choose to double your proficiency bonus for one skill or tool you are already proficient in. This effect does not work for skills or tools that already have a double proficiency bonus (such as skills or tools that benefit from the Expertise feature found in the Bard and Rogue classes). This potion lasts for 24 hours.
