[3.5] Lancing steel scion, deadeye/slayer full physical

https://pastebin.com/Fdxu1bfm

my first attempt at a build for the new skill lancing steel. still unsure about what items would be best to use either duel wield or sword and board. Beltimber Blade / Grelwood Shank are good choices as more projectiles increase the chance for impales.
Reasons for slayer and deadeye instead of champion are the immunity to physical reflect and culling strike, while also receiving the pierce/added projectiles from deadeye for the impale stacking.

any help to refine the tree would be greatly appreciated
