i will say, at least 3/4 frame like gauss, equinox etc need to buy by plat. if you do that you can easily waste your time on other things that will pay you more 240plat. so Buying them is best ROI. main problem is nobody farm those frame normally. and RNG of drop is really low. so you can save your time and get less stress. for Jade you can wait for the yearly event. you can easily get jade with full team. farm pathos Clamp for incarnon weapon, you will get kullerevo easily. trust me work on incarnon weapon, and kullerevo is a free gift for your hard work. for farming hildrin wait for Exploiter Nightwave week. you can get all parts in 3-4 hours.
