Any Profession Lootrunning Crafted Items

Firstly, regular items - Jera, Diamond Dust or Discoverer, 2x Old Keeper's Ring, Knucklebones, and the loot bonus necklace of your choice (I like Emerald Pendant).

Boots (lowballed the base health, didn't include durability booster additional effects)
4x Glimmering Coin
1x Mega Fern
1x durability booster of your choice
Gets -260 durability before accounting for the booster

Helmet (same as above)
[Enhanced Behaviour Microchip][Bob's Tear]
[Familiar Essence][Incremental Mapping Module]
[Enhanced Behaviour Microchip][durability booster]
Gets -267 durability before accounting for the booster

Works best with Mage, since you can heal away the -hpr easily, and also have access to Emerald Staff (honestly mage is so unfair, Emerald Staff and Sage?). If you use it with Archer, I recommend Tier 1 Cooking materials and spam Corbys Innards (although this deprives you of the ability to spam Potato instead for extra loot bonus).

Full build (without Discoverer)

Note, I used average rolls on my custom items. It's possible to get better than that.
