Enchants and Mammon Upgrades

Hi there... first character here, been grinding away in the catacombs and recently picked up a Sword of Revolution.

I also recently came across the blacksmith of mammon, and saw that i could upgrade my Sword to an Elven Longsword for about 480,000 ancient adena.

Ive managed to solo about 100k ancient, and I was thinking about enchanting my sword to make the fights go a little faster. Will my weapon enchants stay on the sword if/when I upgrade it? Also, are dual weapons upgradeable at the blacksmith of mammon?

If you upgrade you lose enchantments.

Yes, you can upgrade duals for other duals. Enhantments are lost in doing so.

but again, you cannot exchange duals for non duals.

this concludes the knowledge of mammon library until some magic Tomas are found again.

okies... thank you for the info :)
