Yes. The tomes can be found in their original location. You can still get 25 to all attributes, without cheating, only by export/import. Just make a character with an inventory full of the tomes, BEFORE using them.

There's an XP exploit in Watcher's Keep at the Machine of Lum. What you have to do is purposely incorrectly enter a combination and there's a 1 in 10 chance of getting 100,000 XP. If you get a negative effect then save scum. All they needed to do to fix it was only allow you to trigger the XP gain once, but you can still perform this indefinately in the latest patch as far as I know.

Personally i don't think developers should waste time fixing exploits that you would not encounter during 'normal' game play. We would be better off letting them use that time to improve the game in other ways.

Besides, some exploits can enhance some peoples enjoyment of the game,,, to each his own.

Admittedly, i did ruin a few games with exploits when i was younger, but hey, i learnt my lesson and nowadays i am very careful how i incorporate an exploit in my game play and without a doubt it has improved my overall gaming experience.

There are so many past exploits which i loved that got 'fixed' in patches and I'm just sitting there thinking what possible improvement was left out because they wasted that time fixing this exploit??

One example of a brilliant exploit was in the game X3 Reunion. There was a trick with going through a gate and you could increase your ship speed. I used it only for my personal cargo ship so i can zip around and get stuff done and that seriously improved my gaming experience, and i was careful not to use the exploit for any of my combat ships because that 'would' spoil the game for me. Sadly they got rid of this brilliant exploit in a later patch, and that was very disappointing, the most disappointing exploit fix EVER in my opinion.
