Originally I started this as a Pathfinder but found trickster was more damage.
The idea is to use Pledge of hands along with another spell echo, which in my testing on the servers fires off about 5 Volleys of Bladefall (which is why I have the count set to 5 in POB but let me know if this isn't correct). I also have Blade Blast as well for the lingering blades.
I have some defenses and level of recovery from cursing enemies and killing enemies that are Withered.
Wanted to see if there was something I was missing as I try to flesh this out more - if anyone wants to review and poke holes, let me know.
