It may simply be because they are all "NMs" but I am having a hard time seeing any of my combos/buffs working. Is this broken? Anyone see anything working?

On Ifrit I do this in this order:

stack Power Surge III
Vorpal Thrust
Impulse Drive
Blood for Blood
Chaos Thrust

After all of this, there is no change to my normal Chaos Thrust that does 77-88 damage per strike.

The combo is successfully being completed, however I also cannot tell if I am gaining the effect of my bonuses.

Anyone else seeing this? Thanks for the help.
