Needed some help with the second question myself:
- A WPS cannot proc from the third strike. But a celestial skill can proc with each strike.
- The Reduced Target’s DA for x seconds of Markovian’s Advantage and Skorpion Sting do not stack. So, you better not assign them to each other. As I did not fully respec my constallations, Skorpion Sting will be my last celestial skill, and I intend to assign it to Blade Trap, which has -% DA. These two effects do stack. In addition -DA (e.g. in MP from Vulnerability) will also stack.
Why would you prefer to use Cadence over Troll Rage?
