Alrighty, I'm at a loss here. I'm trying to find which of two gear setups is more efficient.

Build 1:
Velidreth x2 (1 medium 1 heavy)
TBS x5 (medium)
Spriggan x5 (sharp daggers and jewellry)

Build 2:
Vicious Serpent x5
Spriggan x5
TBS x2 (for the health bonus and undaunted 9 passive)

Build one goes Thief and Shadow, build two just thief.

My question is, are both builds equally viable or is one more than the other? If so, which? Damage tooltip is higher with B1 thanks to shadow, but sustain and movement speed are better with B2. So doing less damage but faster or doing more damage but slower.

I'm stumped.

Edit: I know 5 vo, 5 spriggan and 2 veli would be better but atm these two builds are the options I have to choose from.
