The Combining Stone

This piece of magical rock has the power to combine the magic of any two magic items which touch it. The magic of the second item to touch the stone is drained into the first item to touch it.
Abilities drained into an item of an incorrect type become latent, ie if a +1 sword is drained into a displacer cloak, the +1 hit / damage magic becomes latent in the cloak, if the sword was intelligent, the cloak would become intelligent.
Weapon powers should work if transfered to a non weapon.
Special abilitys like the Vorpal sword will only work in a bladed weapon, and will become latent.
Weapon/Armour Pluses are not cumulative only the highest is retained and any special bonuses are retained (ie a +1 +3 vs magic using's sword combined with a +2 sword becomes a +2 +3 vs magic using's sword).
The combining stone can be used once every 50 years.
