Knowing people, I'd probably say fusion augments is a good way to go. Tank Augments could be a fusion of Health, Healing, and Damage while Explorer's Augments are Mobility and Light. The fusion augments require the individual ones in order to be made, plus maybe a little extra, and eventually end at Omni Augments that requires the fusions. Having tiers for the fusions, at least starting with the tier 3 augs, wouldn't be bad either.

BconlonGaming's Combined Collars mod is a good example of this and is compatable with the Craftable Pet Collars mod by marciocjr13; basically the same awesome thing you're doing here.

@TheTacticalGamer Combine augments together to create a new one that the first idea that i want but there is already a mod call Combineable Augments which is better, you can combine all augments into one.

Can you alter the swimming augment? Make so it increases your horizontal swimming speed, but doesn't affect your (or doesn't affect as much) your vertical swim speed? My game once glitched a swimming augment and it was a thing of beauty... until it reverted, and swimming upward was the only thing it the swimming augment enhanced.

can you make an aug that uses healing materials in your inventory automatically if you reach a certain HP, you can make varying versions that have improved refresh rates, the better the aug the harder it is to die

What about an Ice Thorn Augment? Makes the enemy that touches you get damaged and get slow!

Moon breath augment

Could you offer augments without an animated effect? No particles or anything that displays things are happening? Maybe superpowers like electrokinesis or stuff like that?

Elements Resist 1 & 2 id?

Could you do one that has electrified animation?

make the money planet and divine planet augments have a version of their augments that is combined
