If I am reading that right, those things cant roll double on the senors or processors. I was doing processors too for a while looking for a double. At least memory can, so I can go farm those. And just pick a processor with a resist for each element it seems.
Looks like I will do a double HP aux, Double Def memory, then just 1 of each for the other two. At least until I can get the hardmode set ones, like supernova for bunny, a firearm atk one for gley etc.
Keep in mind that different slots have different max HP and DEF mainstat values.
Aux Power - 4683 DEF / 646 HP
Sensor - 2385 DEF / 646 HP
Memory - 4683 DEF / 484 HP
Processor - 4683 DEF / 646 HP
So that means you always want HP on your sensor and DEF on your memory. The other two you can just do whatever.
Wish I'd known about doubles not being possible for Sensors or Processors. I probably threw out actual best rolls while looking for something that doesn't exist. Seems fairly simple overall though:
Aux (farming) - Any/Kuiper/Module
Aux (colossus) - DEF or HP/HP/Fire Res or HP Recovery
Sensor (farming) - Any/Consumable/Character XP
Sensor (colossus) - HP/MP Recovery/Chill Res or HP Recovery (Max MP is good for speedrunning dungeons)
Memory (farming) - Any/Gold/Firearm XP
Memory (colossus) - DEF/DEF/Electric Res
Processor (farming) - Any/Equipment/Item Acquisition Distance
Processor (colossus) - DEF or HP/Toxic Res/Shield Recovery
