Any Profession Need Help With Items

Anyone have a good Recipe for the following Items?
- Ring with 2+ attack speed
- a good thunder or fire spear
- Items with a lot of melee dmg in %
- helmet with melee dmg % and earth dmg %
Thanks for the help if you have any if these recipes

 

#1 not possible since there are no +tier jeweling ingredients (because they would be absurdly overpowered).
#2: 2x T6 powders of that element, 3x or 4x Enhanced Potential Microchip, and if you chose to use 3, use a durability booster in the last slot.
#3 do you care about -tier? Also what type of items?
#4: If you don't care about -tier, use Ironwood Chips. If you do, spam Galvanic Stone and Enhanced Potential Microchip.

 

#4 Cursed Wings, Mixed Mineral Deposits or Enhanced Pathfinding Microchip are also good options, Enhanced Potential Microchip is way too risky in my opinion.
