I seek it to first paralyze Gobul, then send him back where he came from...
BTW, the only Gobul part I can actually get right now is Gobul Whiskers.
I currently have access to:
The entire Light, Medium, Heavy bowguns
The Jaggid Fire parts
The Tropeco Gun parts
the Royal Launcher parts
the Barrozooka Barrel.
Also a good armor would help, too. I am willing to farm Quru or Ludy.
