What was the name of this Feat/Item?

What was the name of the Spell/Feat that made an item into something like a lich's phylactery?


If it was a spell then it was in Tome & Blood (and it wasn't updated in Complete Arcane).

There's Hide Life (9th level sor/wiz) in Tome and Blood. Targets a body part which you can then remove, though.

I forgot that Hide Life used a body part, not an item.

I still wonder what the feat was, I think it was in Dragon Magazine though.
