I've always felt that Splendor was the most underwhelming domain, so I wanted to give it some more powerful options and I started with this ability. How do you all feel about it? I'm interested in all forms feedback: power level, how understandable it is, how fun it is, etc. I would eventually like to make it available to my players!
