Finally managed to complete against the rope quest w/o losing an apprentice family at lvl. 12. No movie, but here are few tips. Once you enter blackpits, sneak to the left, and go to the dwarf cellar. Do not interact with any of the magisters, as if you don't have extremly high persuasion, you don't stand a chance. Stock up on water/air/physical spells. Pyro won't be of any help at all. Once you get to apprentice hanging, get up all of your characters to upper platform and initiate conversation with the main white magister (lvl 15). Meanwhile, teleport the magister as far away as possible (closer to the gate). The fight will be initiated, yet one if your characters will be locked in conversation with that magister. Take out the ranger magister, and complete the conversation. The void creatures will appear. This is very difficult fight, so save often. Your main goal to use teleport to throw every void creature/magister from the top platform, and heal/fortify the apprentice. Void creatures will be fighting magisters, you need to take them out from the top using air/physical. Once the fire creatures arrive, use air/water/physical on them. Try to pin them at lower levels for as much ad possible while taking them out with ranged attacks. Ranged Ifan destroyed most of the voids for me. After the fight, go back to apprentice family, and the fight will begin as soon as they see you, so use sneaking to tactically place your characters according the ability. Once again protect the apprentice. This fight is much easier (lvl 13-14 magisters), yet he can still die. After the fight, recieve your prize from the apprentice, and go back to the witch to increase your source. I'm sure there are easier ways, yet i really enjoyed this one as an underdog. Hope it helps.
