I don't see how this is experimental lol but there are a few skills I'm wondering why you got:
Fighters High, Short Rest, MP Boost, Sober Analysis. Knuckle's don't exactly burn through MP so these really won't do much lol.
ATK UP+ Smash(Battle Tree)+Knuckle Mastery. I can understand why you got these but I think points would be better spent elsewhere at the moment.
Smash and Sonic Spike(especially this skill) should be 10. Light Armor Mastery should be maxed. HP Boost should absolutely be maxed. It would also be worthwhile to get at least 1 point into Earthbind, 5 into Bash, and 1 into Shell Break.
Def Up 5+Eva Up 5 may be hard to fit into builds currently.
Gear:
Volcanic Claws are great(this is Volg Claw)
Replace Light Silt with Dagger(the dagger named "Dagger")
Forest Wolf Garb is great. The new Fight Gear is pretty decent too, Forest Wolf Garb is better in general though.
Crystal Earrings are a no. Dawn Hat(Crimsosh/boss version, not the regular one) is the best for Knucks currently and increases Evasion
Speed Talisman or Sofys Talisman are great for Special equips.
