Ill just copy paste everything from my reddit post because ive been working on this for nearly 7 hours now and im feeling a bit lazy.
extra link for easy access: Odyssey suit/wep upgrade cheat sheet.
EDIT 2: most of the pages have now been completed baring some additional formatting and coloring to make it clearer. the first page should show the basic information and the engi mods page contains a list of ALL ITEMS obtainable in odyssey. if they are needed and if they are not (so you can sell and trade with ease)
im now working on a build designer on the last page (WIP).
the goal is you can pick what upgrade level you want for each item and itll spit out the required materials for that upgrade and mod selection. (wish me luck lmao).
if you have any requests or notice anything is wrong please let me know. thanks. feel free to share the link but refer to to this post so i can get some of that sweet reddit karma.
So the top left you can see we have weapons. this includes all the materials required to upgrade all combined weapons from 1-5.
under that we have suits. the same goes here all combined suit materials required to go from 1-5. the next column shows if that material is tradeable at a bartender.
The grey/black sections are the bartenders trade options. all 3 sections chem/circuit/tech. the value of each component (and its barter up/down value) and if that component is required for a upgrade (Y) yes or (N) no. a red (Y) indicates that component is required for a MOD. So any component that just has a N indicates that is not required for any known upgrade/mod yet. NOTE: some mods have not been discovered and these materials may be required for engineers that have not been discovered/unlocked. however id say you could just go ahead and trade these for needed components as the time taken to unlock the next engineer would probably give you enough time to farm up the components again. and for example if you aren't going for mods yet and just want upgrades. you can go ahead and trade the ones with a red (Y) too.
The SUIT MODS section and the WEP MODS section includes MOST of the known weapon and suit mods which can be found in the ENGI MODS page at the bottom of the sheet.. it shows the Type of component. tech/chem/data/circ/compo/goods(components/goods, these are like circ/tech/chem but are generaly not tradeable and just random untradeable things like power regulators/drugs found at various sites/settlements/bases/crashed ship/satellite)
the best sources down the bottom right will eventualy include links to guides that will explain how to farm/obtain the materials/components.
(As i was making it i became aware that the red/green color combo may be difficult for color blind people to see. i don't know enough about color blindness to do anything about that right now but you can simply select the whole sheet and change the background color to black/white and the text to black/white. the color isn't really needed but it helps define certain things that aren't formatted well yet...)
