i just now made it to the dock colony,The investments payed off again..they kicked me down a Dragon Skull for KOS-MOS.
It's the weapon she uses to shoot at the Gnosis Mother Ship, when she's standing on the escape pod right after the whole Woglinde event. It's a beam weapon..
Also the EVS for the U-TIC battleship has a crazy ass enemy on board. He's located in the room next to the one where JR's soilders were interogating that UTIC soilder for the card that opens up door 3. He just stands there when you walk in, you have to go up to him to fight. His AWGS is powerful wiped me up 3 straight times. I'm going to have to come back after leveling up some to beat him. Even my AWGS don't stand a chance against him.
