Scroll of disenchantment (or wand): rare like SOCM or wand of mirroring/cloing. When you read/use it, it takes an enchanted item (armour/weapon) and removes its enchantment but gives you a enchant armour/weapons scrolls. Eg. find meteoric steel mace +6 but you are a sword guy, poof you now have a regular old meteoric steel mace and 6 enchant weapon scrolls. For those who might say this is unbalanced, its no worse than a wand of cloning/mirroring.
Wand of transfer enchantment: takes a pile of 5 items with different enchantments and combines the enchantment into one item (at the top of the pile). The regular enchantment buffer above 5 would apply (eg 5 +5 items would not give you a + 25 item, probably more like a +8 to +10)
