dtgreene: I have not found any way to raise stats above their racial maximum (aside from hex editing, of course). Using Ankhs or Protectorate will not raise stats above there maximums, and changing a character's race to Devilish (repeatable event in hidden room in final story dungeon B5F) will lower any stats that are above their new maximums.
Ok, I have found that racial stats are maxed at +10 from base stats, and no matter what you do, you can't have higher than that. If you hex-edit them, after leveling-up you lose whatever you had over racial maximums.
Now interesting things, which confuse me. So there is floor master Vovalketer, he has following items equipped:
1. Mork Cricketer (Item ID 698).
2. Vorpal Sickle (Item ID 653).
However, according to database (Monster3.csv, line 340 in properly imported file), Vovalketer has "Strike" (Item ID 653) equipped and not "Mork Cricketer". Nothing in Monster3.csv shows that Vovalketer has that weapon.
What is also strange, Vovalketer is dual-wielding, AND has 2 Actions per combat round. But when he attacks 4 times in a row (apparently, he has a chance to attack only once too), his 1st attack is called "Lightning Strike" instead of "Mork Cricketer", even though it seems to deal same amount of damage.
Also I wonder about "Physical Attack Power" EX-Skill, does it round down, and does it apply per attack or to total damage done. I need to do more testing here.
Those databases are quite interesting and allow to make 100% accurate item tables and any possible enemy encounter per dungeon floor. It might help, when you want to catch each and every monster and item for Castle Library :) Quest Flag database also looks "approachable", but this thing is less or more covered in Japanese wiki.
