Embed Enchantment

[Andreas the Apprentice]

I've just played my first two games as an Enchanter, and now I have a question about Embed Enchantment.

How many instances of Enchant Armour/Weapon does it affect after a given battle?

A little context: We played through Haunted Houses, and since Wraiths are immune to non-magical weapons, I enchanted a lot of weapons. According to my notes, the 2-handed weapons of 4 of my infantrymen, as well as the handweapons of my wizard and apprentice.
How many of these can I keep as magical weapons? End how many times will I have to roll for Embed Enchantment?
The book says

This spell causes any Enchant Armour or Enchant Weapon spell that is still active at the end of a game, to become permanent

My english isn't perfect, but wouldn't this mean that a single succesful casting of Embed Enchantment would make all 6 of the above permanent?

I have read it as Embed Enchantnent, makes permanent a SINGLE magical enchantment.

Remember, you have two spell casters, so if lucky you could make permanent two magical enchantments.

That was my initial read as well. I assume we all agree then?
