As per the standard 3.5 character creation rules.
Roll 4d6 nine times.
Drop the lowest die from each roll, then drop the lowest three rolls.
Use the remaining six to assign to your character’s Attributes.
Fresh starting characters are either at Level 1, or one level lower than the party level.
For a fresh start with all party PCs at level 1, a PC with a starting level adjustment needs an additional amount of experience points to advance their character level depending on that level adjustment.
Example…A PC character starting as a Tiefling must take a +1 level adjustment. Hence he or she would need to accrue an additional 1000 xp per level.
