This attack never executes. I've tried the following several times in different scenarios:
1. Set up a single enemy face to face, trading blows.
2. Do nothing for a few secs to prevent lag problems from interfering.
3. Click on Shrouding Strike.
4. Observe animation but no notification on screen or in log of hit/miss.
This happens every time. The animation is there but there is no attack. Bug or am I overlooking something?
