Stage 1 Poison Rune
This was the third recipe I came up with, mainly to give the Glasses of Slime some good use. Given rarity is apparently the motto here, I'm thinking something like... This.:
Crafting Requirements: 50 Glasses of Slime
Stage 1 Sharpening Stone
A commonly-suggested recipe, and, well... Heck with it, Sharpening and Hardening Stones are as basic as enchantments get.
Crafting Requirements: 50 Metal Chunks
Stage 1 Hardening Stone
Again, commonly suggested, no skin off my bone.
Crafting Requirements: 50 Monster Rocks
Bone Weapons
Okay, so for these, you would need Monster Bones to craft. Here's how they would go.:

Bone Dagger: 5 Monster Bones
Bone Spear: 15 Monster Bones
Bone Trident: 35 Monster Bones
Bone Dagger:
Power: 40 (1.25x Lutan)
Crafting Price Modifier (weapon): 0.9x
Crafting Location: Renegade Hideout
Bone Spear:
Power: 61 (~1.25x Fractured Axe)
Crafting Price Modifier (weapon): 0.9x
Crafting Location: Renegade Hideout
Bone Trident:
Power: 98 (~1.25x Skull Spear)
Crafting Price Modifier (weapon): 0.9x
Crafting Location: Illegal Yard Sale
Crabhammer

For it's details, well...
Power: 72 (~1.25x Caliburn)
Crafting Price Modifier (weapon): 0.9x
Crafting Location: Cheapo's
Crafting Materials: 40 Crab Legs
Mhmm. So yeah, there's about what I can come up with.
