Compiled a little SQL together containing a few useful SQL Statements people have come up with. Simply source this into your database and it will:
Give all mobs with instant respawn a respawn time of 1000;
Give most newbie mobs loot appropriate to their race (rats drop rat items, skeletons drop bone chips etc);
Fix the damage for all mobs (no more level 1 mobs hitting for 400 etc);
Fix the HP for all mobs (no more level 24 mobs with 2k HP etc);
Fix the aggro radius so lower levels have smaller radius;
Fix most classes (no more merchants where there should be a GM);
Fix all starting items;
Fix all zone points;
Note - Most queries will only affect mobs with either "a_" or "an_" in their name to prevent customs and boss mobs from being affected, however some custom data might still be changed. Better to create a backup so if this does mess things up you can restore.

If it messes everything up, don't blame me. Just trying to help.
Good luck, Monrezz.
