If you play a character who knows how to enchant items, you can now use the online treasure system to perform your enchanting between games. Just go to the Treasure tab on your character sheet, click "Enchant" next to the equipment you would like to enchant, and select the enchantment you would like to add on the following screen.
As always, the system will let you know what enchantments you can use on a particular treasure, whether or not it can be enchanted further, and whether or not you have all of the necessary ritual components to perform the ritual. Assuming you have everything in order, performing the actual enchantment should be a cinch, but please let me know if you encounter any problems.
I'm still working hard on this stuff. Next up, I'll be adding the ability to put your treasure up for sale in a public bazaar, so stay tuned.
