Logik is right! One of the best back pieces for PUP hands down. But if u can wear an Amemet +1 or Cerb dont even think about to switch it out for this one.
1% DA is going to be given you less than a 1% increase in damage. That's an added hit every 100, whereas the ~9 (7+1.5~2.25) from foragers with a high likelihood of an fstr will give you better returns.
However, for the non-foragers jobs it beat out the previous 6atk alternative.
Brutal is awesome because the next best option is 3acc or 6atk (DM and AN earrings can go in other ear).
Pole strap alternatives are basically 2acc/str, 4stp, or crit.
Back piece is almost exclusively limited to attack ones or cuch for the jobs that can use it.
For SAM, Will most likely beat Foragers/Amemet +1 for TP since it actually increases the rate at which you get TP rather then just DoT since SAM is 30/70 DoT/WS, a very nice 1 hit WS back piece, debatable whether it will beat pieces with actually STR+ for consistency, but definitely will help yield the high numbers with the DA+
