Some Vendor Recipes Ideas

These are a few vendor recipes I thought of. I figure the "upgrade" patterns could be introduced by Act 4 vendors (ie. they offer the item for the price of it's components). The rest would just be recipes when you sell to vendor.

Upgrades:
10x Blacksmith's Whetstone --> Cartographer's Chisel
15x Glassblower's Bauble --> Gemcutter's Prism
2x Alchemy Orb --> Chaos Orb
2x Scouring Orb --> Blessed Orb

Recipes:
1x Red Gem + 1x Chromatic Orb --> Ruby Orb
1x Blue Gem + 1x Chromatic Orb --> Sapphire Orb
1x Green Gem + 1x Chromatic Orb --> Emerald Orb

The Ruby, Sapphire, and Emerald Orbs would be Chromatic Orbs that are slightly biased toward generating sockets of their corresponding color.

Updated.

Figured I might get more responses if the recipes were more "hardcore" so I made them more expensive.
