Galvanizer...mmmm...I love watching ValorEdge counter so much against NM's when that attachment is paired up with Gnarled Horn and/or Roaring Laughter, especially against Chloris, that poor *** just gets raped left and right.
Interesting note, can automatons be doomed? lol.
I'd have to say the skillup attachment was one of my favorites. Saved a lot of time when i was skilling from lv75->99. For actual use, definitely turbo charger and the armor plates post-patch.
