Do the dark sector excavation on Europa

Oberon was once our credit king, now lord Harrow shall reign supreme. Do void fissures, get flooded with his chassis, sell them for good. A good side quest to keep those blueprint costs at bay.

Profit-Taker drops 125k,

250k if you use Chroma 4th ability just before Profit-Taker drops,

500k if you did above with booster.

Yep, get a booster if possible and get a good squad for index. I use inaros and a heavy radiation build on a vaykor hek.. magnetism on primary and viral on melee is key.

The reason I find it hard is because I tried the one for Glast gambit and it was hard

Don't compare. Your friend is literally a bot, and nef is practically cheating.

If you have a decent weapon for index, bring a tanky frame. I recommend wukong, as you get 3 extra lives that dont force you to drop points, and his cloud form is good for getting to the goal quickly. Another option is to play gara. Build up damage on your glass armor and you will both be hard to kill, and kill everything just by touching them. Also you can set up a wall at the enemy goal post
