Power cards?

I've made a few macros that work well and would love to use the power card script (!power) and found the wiki on making powercards. <a href="https://wiki.roll20.net/Custom_Power_Cards" rel="nofollow">https://wiki.roll20.net/Custom_Power_Cards</a> . It seems clear enough from the wiki instructions, but I can't seem to convert any of my macros to power cards that work. Nothing even shows up when I try to test them. Any advice?

You have to be in a campaign run by a GM who is a mentor that has the power card scrpt installed.

Thanks HoneyBadger. How can my GM install the power card script? Does it cost extra?

Yeah. You have to be a mentor which is a $10/month subscription.

Ahhhh ... thanks for asking, Emily P ... and answering, HoneyBadger ... I was wondering the same thing.

Note that only the person who creates the campaign needs a Mentor subscription. If you've got a group of friends who play together, you can pitch in to split the price (see "Give Gift Subscription" on any user's profile page). If you switch around GMs, the person with the Mentor status can create the campaign, promote someone else to GM, and then click "Re-Join as Player" (at the bottom of the settings tab) at the start of each session. Of course, if you're joining campaigns with people you've never met before, that strategy doesn't work so well.
