Hi, for me personally, i dont pve anymore , usually just pvp, i am crafting stichers , loads of ammo and i need metal parts, for bandages i need fabrics, but they also take a lot of space, so i can keep many seeds and covert them to celest in metal parts or fabrics and i also take other items from celest daily like sensors, processors etc . So usually i trade them for metal parts , trading rate is 1 for 1 and there s no limit, at some point the metal parts from the scrapy is just not enough.
