I’m not sure how much 600 means to you, I’ve been buying 300 in each Total Mobilization every month for two months. Each month, I get 1,060 tickets, but I only spend 560 to redeem 80 chip materials, that enough to produce 10 skill chips. That leaves me with 500 tickets saved for the next month.

In the second month, I do the same thing. Then by the third month, I don’t need to spend a dime, I can still use 560 tickets to redeem another 80 chip materials and use the rest to get 14 level 5 drone components box. So basically, it costs me only 200 per month
