... something horn? It was in the forgotten realms book if I recall correctly, and it basically did the sunblade thing, where it gave the weapon the damage of a weapon one size catagory higher without increasing its 'handiness'... was a +1 I think... possibly +2. I don't remember what book it was in, but I got campaign setting/player's something or other running in my head so check there.
Hey, I was wondering if anyone knows/remembers the weapon property for making a weapon 2 size category smaller. So when you weren't using it you could make the large weapon small for storing. Then when the battle broke out you could draw it and make it large again. Does anyone know where to find this or even better the price of it? I remember it was just a flat cost to add onto it. It did not cost or have a + anything.
That is the Hideaway weapon property. It's on page 36 of the Magic Item Compendium. It costs 2000 gp.
Or Shrink Item spell made permanent.
