Sorry this is a little late, I've been hella busy lately!
Suprised nobody could answer this before!
Alright. I've got over 12 mixed sets, I've found this is entirely possible but extremely difficult to pull off.
It's easiest done with relics. I suggest the following skills:
- Edge Lore
(Attack up L/sharpness +1)
- Nimbleness
(Evasion +1/Evade dist +1/Constitution+1)
-Challenger
(Atk/Affin+)
You can however obtain a Furious Rajang mixed armour which combined with other pieces and possibly a relic can give you
- Edge Lore
(Atk L/ Sharpness +1)
- Challenger +2
- Evasion?
(you will have to gem on evasion somehow, maybe with a relic or charm)
Keep in mind this set is end-game top tier.
Relics will trump all armour and weapons in the end! You'll want to aim for those pieces with +5 of the skill you want.
These skills are not easy to come by, and you can't make decorations for them either.
Except for the challenger skill!
Also, I believe might seeds stack with food boosts and HH boosts!
Hence why the wide-range skill is so good for extra buffing!!
