I think the possibility to roll back an enchantment and enchant again the item at a progressively increased cost would make it a bit less punishing(the wrong enchantment can make the item useless).
I don’t want this, enchanting is the permanent method of just gemming items.
All enchantments can be done with infusing gems/items these should be able to be overridden.
Enchanting should stay as the permanent cheap RNG method of fulling gemming something.
Thing I don’t like is that it’s the only method to get cursed weapons/armour, and you rely on RNG for the stats instead of infusion.
