Bonjour Francois, bienvenue a Ironworks. [img]graemlins/happywave.gif[/img]
There is always the reload solution - you should have an autosave from the start of the level if you don't have a recently saved game.
Could you give a little more detail about your problem? I'm unsure whether you are being killed by the harpies or whether you don't know how to get to the next map.
If the problem is harpies, you will need spells and/or effects that protect against fear. Summons and disabling spells (e.g. Slow, Web) will help here as well. Use all protective spells you can muster, especially Protection from Fire and spells that increase your saves.
If the problem is that you don't know how to complete the level, you need to collect the flawed gems from each altar, transform them into flawless gems in the Chest of Seasons, and place them in the right order to activate the portal on level 4. Azred put together a little guide to the logistics of it
right here.
In terms of inventory management, leave some of your least useful loot in a nearby chest. Remember which one, and return for it after you have collected the flawless gems.
If your main problem is the harpy fight, post your party here and we'll help you come up with a strategy.
