All That Remains

Head back to the Estate and you'll discover that your mother was kidnapped. If you saved Gascard during Prime Suspect head to Darktown and let him complete his blood magic ritual. Otherwise head to Lowtown and fight through a few enemies. Either way you'll win up inside the Killer's Lair.

Fight through the waves of various enemies in the Lair: Shades, Demons, and Corpses. They are all weak to nature and ice damage so stick to those elemental spells. Eventually you'll arrive at a shrine and a group of skeletons. Kill them off, loot the area for some good new equipment and head down the hall for the quest's final battle.

Based on your dialogue choices Gascard may turn on you or stick on your side to fight Quentin. Either way concentrate on the human mages until they put up magic barriers. Next take down the Desire Demons so they can't prolong the battle with their healing spells. Once Quentin re-enters the fight concentrate all of your attacks and spells on him. As with other blood mages, try to fight with range so you aren't hit with his waves of blood magic.
