I'd like to add a set amount of extra dice to extra damage for attacks and I'd like to have the ability to toggle this option on and off. How would I do this? (e.g. the Planar Focus Fire effect for the Hunter) The buff section only allows values evaluated at edit time. I can not find an option to conditionally add extra damage. Currently I am evaluating an "empty buff"s enabled flag and multiply it with extra damage, resulting in 0 dmg if disabled. But there is always the extra damage noted in the roll. Can I do so without it?
