I've been mucking around with Temple of the Abyssal Winds lately, fixing minor issues and such. While doing this, I found a cool bug worthy of sharing.
The bug is, cast an attribute buffing spell on the main character, say "Strength". This should work if you drink a potion of Strength as well, though I haven't verified that. Then, before the buffing spell expires, finish the chapter. When you start the next chapter, the Strength bonus will be made into a permanent strength increase. Even better (worse?), you can then cast "Strength" again, still getting the buff, and even potentially doing the same trick at the next chapter end.
Anyways, the fix is pretty easy, and this issue is pretty unlikely to come up unless you already know about it and willingly want to cheat, but I thought it was a pretty cool bug.
I should soon do a minor release of TotAW with the various fixes that I've been working on, almost certainly within a week.
