Start with Tac Skill Module, then save 350 Credit to buy Force Core to ally, or if they dont need, build [Helix]. Funnel all your money to Main DPS. The build list is just Example, but you can use any leftover material. But try to keep respectable DEF amount, and atleast 1,6ASPD. CDR is high, so dont hesitate to use W to catch enemy, or protect allies.
