Are there structures with bonuses to reprocessing items? Structure browser only show if there is reprocessing, but do not allow to diferentiate between ore and items. If it even is diferentiated anymore.
So if they exist how do I find them? Are these only in lowsec, I think it used to be the case back in 2017.
There are no structures that give a bonus to reprocessing items, the only thing that affects that is the scrapmetal processing skill. Structures give a default 50% item reprocessing rate, some stations are as low as 35%, so always do it in a structure.
Open the structure browser, remove stations from the filter, check reprocessing filter…then anything that shows will have the same item reprocessing %.
