I completed this for the first time recently. When you play it by yourself at level 1 it is damn hard. I spent most of my time waiting for my fatigue to recover so I could cast heal on myself. Although if I'd known how many herbs were available on the elf island I would have just used fatigue restorer constantly (I had a few hundred spare herbs by the end). Once you get past the initial difficulty, it's quite a good mod. I'm surprised it was not included in the main game.
