I'm attempting to make an attack add-on for use with Combat Expertise that will automatically show what the maximum value possible is for it. Combat Expertise uses BAB to a max of 5. So what I thought should work is: ?{Combat Expertise (Up to [[ {[[@{bab}]],5}kl1 ]])|0}[Expertise] This does not work and the [[ {[[@{bab}]],5}kl1 ]] shows up as text and not a calculation. Is there a way to make this work?
