For Temptress, I used the following with Final / prio 100, and used a Bootstrap to load in the linked AB, which excluded all other powers.
Code:
#trkmax[trkPower] += (#traitbonus[trCharisma] + herofield[acRank].value +1)
This is of course why it's not compatable with another AB, because you can only have a single AB on your sheet. If you don't grant an AB, there's no notation to show the power, nor track the PP.
---------------
Perhaps another approach would be to create the power as a magic item for these edges, granted when the relevant Edge is selected, complete with PP charges.
