I agree. Sure, all depend on inventory at disposition and tendency and preference how to play the game. As SawzAll indicate, sure go first with TORSO and I recommend that as first item to go for. When I started the game with my nice, we had no clue what the heck were for those relics and passed some time to figure out because took very long to get 4 epic relics and I mean months.
Not knowing and never asking to players and just testing how those things will work, we divined our first weapon CORRUPT LIGHT then we understood we needed to be careful.
By the time we got a basic understanding, we got a claw and built the first phys hugger. We were using Mercy with selfish with energy monkey and not fully developed modules. Due to the damage was inconsistent, we opt to divine Mercy and Selfish and took us a very long time because we were solo players to get those relics at high rank.
So far in OKI, I have only 2 premium divined weapons and still the same the Mercy and Selfish. I opted to go for torsos having claws then new adjustment to molten I developed them then new legs as second option in line.
For me, torso and legs come first then a drone because those are part of the mech foundation regardless any other weapon because those parts are universal.
Why do I not have more weapons divined at this point? Just choice for fun. I decided to increase HP with modules but those are the last to do as SawzAll indicated but because I do not have a particular mech preference to use or care about, I went for modules because those are the foundation regardless powerful weapons.
So, TORSO, LEGS and DRONE are priority in my opinion in that order. If you will develop a second mech, keep saving relics for your next TORSO and leg instead to use them on weapons. Finish a 3 set of torso and leg if possible before going for anything else with limited relics.
In my O.D FARM acc, I have zero premium weapon divined just torso I do not have premium legs divined like in OKI and just premium modules divined due to choose to do so. Sure, I do have some some E-M divined due to excess of epic relics in the storage because I do not want to spend gold transforming just leveling up parts.
Remember, TORSO and LEG, it is a HP stablished not a variable of probability like the weapons outputs. You can divine a good weapon but that does not mean you will get the shot to win against a MYTH status weapon or mech. I win all the time without divined weapons vs divined when I play for.
SawzAll always come with good info with logic and giving good tips. Is worthy to read what he is saying.
