The Lich, Ras Frostwhisper

There is but one task remaining, <name>. Confront the lich, Ras Frostwhisper, in his lair. Use the power of the keepsake against the beast - be unrelenting in your actions! Weather the blows that the flailing beast will surely bring down upon you. Do not give in to the pain! When the ritual is complete, Ras will be mortal once more. It is at that point that he must be slain. Strike him down and take his human head.
