Are there any good tips for sneaking past the masks? Because I always have trouble with that and haven't really managed it in any of my playthroughs.
Use Potions of Invisibility by throwing them on your party for the AOE effect.... This sometimes only catches three of them and my fourth party member has to use a second Potion of Invisibility or Scroll of Invisibility. Moreover switch to TB mode and sneak past the masks until you've jumped through the waterfall with all party members. But be careful after the jump you have to sneak a bit ahead, because one of the masks could see your party during their patrol through the waterfall. Also, the waterfall removed my invisibility after I jumped through it. Then deactivate TB mode.
