Soulbound Keepsake

The Soulbound Keepsake is an altered version of the Keepsake of Remembrance, a personal item of Ras Frostwhisper.

The Keepsake of Remembrance was a personal item belonging to Frostwhisper when he was still human. The character turns it into a Soulbound Keepsake by laying it on Menethil's Gift where remnants of Frostwhisper's soul linger from his transformation into a lich.

Later, the character uses it against Ras Frostwhisper, the lich, to make him mortal, before slaying him permanently.
