Magic Item Variant
In one of our in-house playtests, I use a variant treasure system where players rarely get monetary treasure or a chance to loot their downed foes. Instead, the equipment that the characters use frequently goes up in power. Most of the time I identify the item, give the player the amount by which he can increase its value, and ask that he name the item before letting him use its new powers.
While this system isn't exactly like the 289 article, it has worked well in the playtest.
