Bunny build last module

Hello, as title states i'm looking into a bunny build. I got ultimate bunny just today and i upgraded her modules as much as i could. Now i have an empty space (the mp module will be maxed). A guide recommends "energy collection" but i'm not having too much trouble with energy but i want to know waht i can put in there instead. To clarify the build will be used for kuiper mining mission, defense mission and general farming. I have couple of good looking mods to put in here :

  • Iron defense and Spear and shield. (provides same DEF, but idk the diff between SP modif and SP.
  • Time distribution (as i see it the skill cd isn't necessary at all but the hp is nice to have since this build is a bit glass cannon)
  • Electronic syncytium (provides crit res and electric power boost)
  • Weighing the scales (provides shields + cost reduction)
  • Battle of stamina or Stim accelerant or HP amplification (i highly think these are the mods i need to have more hp than 2.8k with some more duration or less mp but if im going to be glass bunny might as well slap on spear and shield or iron defense to have more dmg ? idk)
  • Arche acceleration (but idk how skill speed affects bunny)

These are all i have, any suggestions about other mods are welcome since i dont have knowledge about legendary mods and some other rare mods. Thank you !
