The Sword of Grief can be upgraded by Cespenar, which requires the Heart of the Damned and some gold. Unlike most weapon which can be upgraded, this does not increase the level of enchantment and as result of doesn't improve the current properties, it adss 5% magic resistance to the wielder and each target must make a save vs. death at -4, or they will be level drained for one level each time.

It's a very powerful two handed sword and probably the best two handed sword for non-paladins classes, as they can wield Carsomyr.

In-game description before updating
"This is one of the many weapons of the great hero Siegfried. The blade is particularly sharp and well balanced, and in a certain light one can see the faint image of a serpent within the hilt."

In-game description after upgrading
"Siegfried's fearsome blade is even more powerful with the Heart of the Damned set into its pommel."
