You survived the Djinn? I froze him and then used meteorstrike. Don't forget to take the letter with you, it shows Elrath's treachery and - very important: Take the 2 cure potions in the SE corner, too. I know, you have 3 patients to heal and only 2 potions. Goldmond, a German gamer, found out she could pickpocket one after giving a potion,so you have enough for the 3rd patient. The original game plot was this: Even a hero has to decide between life and eath, but the Larians didn't reckon what gamers could think up of. You can choose to kill or - as long as you have 2 potions - you can split them by dragging them into your inventory and pressing CTRL. The split pane pops up, type in a negative number and you've got more than you need. BTW, even if Tibus is Sir Dante's son: You won't get a reward for saving his son - that man is a miser.
