Can you enchant both types of enhanced crossbows. Cause when i go to enchant them, after I select an enchantment it doesnt say the enchantment or strength. Also, if you can enchant them, does it work properly?

I enchanted the enhanced steel crossbow. Even though it does not tell what this enchantment is in the weapon description, the enchantment did take since I could see the targets I shot catching on fire.

Its the same for silver swords (that does bonus damage against undeads). It works just fine, its just that the info panel is to small and the text ends up outside it = now showing (thats my teory atleast).

I recommend using a fire enchanted enhanced crossbow with explosive fire bolts against vampires xD BURN BURN BURN.

Yes, you can enchant them. Just add the enchantment to the description so you can keep track.

Just select the enchantment for another item and look at the magnitude and charges. Then just go to the crossbow and apply it. It's the same but It would have been nice if you could actually see it.
