Hints About Mod Leveling

[radthezero]

So, here's my problem...

I've been playing since around update 6, got the changes in mod system since the beginning, yet there's something that bugs me. I can't seem to level a couple of my mods past their current level.

I am talking about Hornet Strike, Serration, Vitality and Redirection. All of them are level 6, and I'm having a bit of trouble to get them past that.

 

So, any hints? Farming spots, maybe? A good place to drop high-level Fusion Cores or copies of said mods? Any help is apreciated.

they just get extremely expensive to upgrade. you need hundreds to thousands of mods. throw everything you dont need into them :D

Just farm defense missions to get uncommon and rare 5s.

I prefer running mobile defense (Kappa or Kiste).  There's a little more variety rather than standing in a single spot the whole mission, and the enemies tend to be mostly funneled through a couple main directions.

When leveling multiple high level mods with different polarities, don't forget that matching polarities provide an extra boost.

I'm at the same point with the same set of mods; just gets really expensive.

Additional levels increases by powers of 2 per mod level (2, 4, 8, 16, 36, 64, 128, 256?).  This is skewed a bit depending on the polarity of the mods you're fusing and any fusion cores used.
