So, during the last game I was using IF. However I mostly used it only with one of my attacks. The first time I used it on both attacks I got into sort of a debate with mate wether I was able to use it on both attacks (similar to Warlord ) or if it was only once per activation (à la Screed).
Now we've Rock-Paper-Scissored it the first case, but I thought it might be better to ask for proper clarification here.
