I'm using Theorycraft 1.06.5 and it shows the dps or hps, and it has other options but it doesn't seem to have an option for mana costs. I tried editing the code myself but I'm still a noob with lua so I couldn't do it.
This is how the values show in TC, I would like to change the number in the healing touch rank 4 icon for 185 which is the mana cost of the ability instead of 400
