Herblore in Daemonheim is only accessible to members who are doing complexity 5 or 6 floors. All Daemonheim potions are 1-dose only, and most boost multiple skills at once. Some obstacles require a potion-boosted skill level to pass them (e.g. "You need a mining level of 103 to mine this rock...."). For skill doors, Portents of passage can be used instead of potions. Players are able to bind one potion to a special potion slot and use it in upcoming dungeons, similar to other bound items.
