The morph of adding one second does work. With animation canceling, I can usually get it to last the entire fight with no problem. Unfortunately, FTC doesn't seem to update the buff count-down, and I'm not sure if other add-ons have this problem as well. As for the damage boost, I seem to do more DPS overall when using it, but I haven't paid attention to individual numbers.
i just tested, only about 10% of the time i get a damage boost(maybe it is critical hit?).. also the morph of adding 1 second per heavy hit doesn't seem to be working..
