In the text of a Trait, have an inline roll so that when i click on the trait, it rolls the dice?

For example, I have Second Wind on a character, and I want the roll for hit points to happen when the description of the trait is sent to chat. I tried this: " You have a limited well of stamina that you can draw on to protect yourself from harm. On Your Turn, you can use a Bonus Action to regain Hit Points equal to /r 1d10+4 (Fighter level). Once you use this feature, you must finish a short or Long Rest before you can use it again. " That doesn't work. 

replace "/r 1d10+4" with: [[1d10+4]] Bonus: replace "+4" with "+@{level}"

Hi Waargrin! More info: The double bracket construction Gauss is providing is called an inline roll . You can still see the individual dice and the formula that produced them by hovering over the result in chat.

Thanks Gauss and Keith!
