 
Hello,  I would like to know if there is a formula to "deduce" automatically a "number x" on one of the 3 key bars.  For example, you launch a power using "3 mana", and automatically it reduces iby 3 on the "selected" character in his pool of mana.  (I play with the basic Roll20 only !)  Thanks for sharing!  Fenrilh
