How to farm speed mods?

It depends on what you need. If you need quite a few then farming the last tier of the mod challenge is best. You’ll get a lot of speed arrow that way as well. If you’re just looking to upgrade a couple mods or one character buying them is going to be better. I’m a newer player and need to equip a ton of characters, thus the mod challenge is best.

does the challenge matter? Or do i need a resistance team ?

luck

I allocated 3 weeks worth of cantina energy to only simming tier 3 mods (mostly speed and potency), but ended up with some really good mods that way. I wouldnt call it efficient, but just suck it up and do it.

Once you have all the necessary cantina toons (ha... Ha) go crazy with the challenge. Personally, I still need to finish CHS and DT before I exclusively do the challenge for any extended period of time. As it is now, I devote about 48-80 energy to mod farming and the rest to CHS.
