I always lost 3 stats pts in toto, the first 3 ones (strength, agility, intelligence) - but I heard from gamers just losing 3 on one stats. So, I guess, it's random.

Hmm, and I vaguely recall a gamer in the old forum stating: If your HP are high enough, you don't lose any stats - but I can't confirm this, maybe a version difference.
