Best way to get 3 slot weapons + parts?

So, I've noticed that some of my parts have 1, 2 and some have 3 slots. These slots are used for when "tuning"? Is it recommended to only tune parts that have 3 slots or does this not matter? I haven't tried out tuning yet because I'm not sure which parts/weapons are worth tuning.

Arcantus/Luck?

More slots = more tuning, it doesn't matter otherwise. You can tune a 1 slot if you want, it's just that tuning supplies are in demand so you might want to save it for a 3 slot of whatever weapon/part you want.

(Remember kids, always use protection.)

Weapons are more worth tuning than bots, and with weapon specific tunes, rather than stat tunes.

Personally, I'm just saving all my tune items to get a Great Capacity upgrade for a set of legs... Those are epic level goals I'll probably never reach.

get lot of friends, most of my 3 slot robot part are comes from friend arena gift

for weapon, you can try your luck in arcantus for grind em and hope found any 3 slots... more chance if there's multi exp event or Fever Time

or another method, you can spam mission , SKILLFULLY!!! if you can complete mission with high score , high Brave and less death, you will be better rewarded... especialy if your mission friend also skilled
