though the guide has helped me a great deal with how Im going to build the claw side of my sin, I still have a few questions about my traps. Do most people recommend 1 or 20 in death sentry? And no where in the guide does it mention blade shield though it seems like it would be quite effective with this build. Any comments or suggestions regarding traps?
1-20 point DS is matter of personal preference and style. If you put 20 points in it, the CE might become to dominant to your taste. It will also cost you a synergy of course. Personally I always it max though, unless style reasons demand otherwise.
Blade Shield is not particularly useful. It hits very slow (once per second) and with low damage. Things like OW and CB don't work with it either.
also, unless im misunderstanding 'next delay' wouldnt the third charge of CoT be almost completely pointless?
Not pointless. You can even get around the next delay by using DTail as finisher. It gives knockback which pushes the monster just far enough away for the next delay time to pass.
Basic Skill layout would be:
MA tree
20 CoT
20 Phoenix Strike
1 in all finishers
Shadow tree
1 in everything
Trap tree
1-20 Death Sentry
With the rest of the points you can do a few things like pumping Venom/Shadows, get another elemental skill (FoF/BoI), give DS more shots (Fire Blast). A point in Blade Fury, if you have a nice weapon for it, is always a good idea.
Gear is not any different than a regular Phoenix Striker.
