For all who have trouble here, again preperation is the key:First the shopping list:1. Have enough alcohol and or ingredients / or have your potions already ready - I am just stating that bc in this act strong alcohol is not soooo easy to come by (especially on neutral): Kalkstein sells though2. Before entering the mansion take a couple of "long" potions, if you can albedo base (at least one of) them, you can get away with three. Good choices depend on your character,I had an Igni user, so full moon and petris philter were good. Possibly also Mariborforest.3. Meditate for an hour to get rid of toxic effects.4. Use the old standby: Tawny owl, swallow, possibly willow, each with a different second effect. (for the Kotchey it might be advisable to substitute kiss for willow as its specialty is bleeding - I didnt and survided but that took me a white raffods)5. If you can get through the initial monsters on rubedo alone postpone swallow till shortly before the fight.6. If you have runestones, you might just as well use them, there are not many things to save them for at this point (one for silver sword now, one for steel for azar, later and two for the epilogue...)The fight:If you did all or most of the above, the fight should be relatively easy (I know it can be annoying if someone tells you something is easy - but with the stuff above it is).I just fried the hell out of the thing with Igni, resorting to running when low on health (remember I forgot the kiss potion - with it it should be possible without runing).If you are a swordsperson, you might want different long potions and look at the swordstipps posted before.After the fight:Might be a good idea to stop at the nearby fireplace, meditate and repeat the above procedure fo the next fight with Azar (here willow is much better than kiss, of course...)Happy hunting
