Need Help Tweaking Lan Server

[blackwaterr3]

Hello i making a EQ Lan Server and for the past few days i have been
messing around with SQL trying to get the EXP Gain from 100% to 750%
this is as far has ive gotten, i am Using Build "EQServerPack-Maps-4.0-1110a".

mysql>show databases;
mysql>select database()peq;
mysql>use peq;
mysql>show tables;

~
!rule_sets
!rule_values
!Variables

These are the only tables i see that would have the exp gain info under
them however i dont know how to find out which one does and how to change it. Im VERY new to using sql so can you help me do it step by step.
