Here's a small compact version of the query. All you need to do is edit the areas and run this. It will update anything with a POSITION of 8 or less, and then the 12.
Code:
UPDATE cq_item SET amount='28800', amount_limit='28800', gem1='18', gem2='18', magic3='255', warghostexp='1536', 'eudemon_attack1='255', 'eudemon_attack2='255', 'eudemon_attack3='255', 'eudemon_attack4='255', 'special_effect='255', forgename='Darthling' WHERE player_id='14942916' AND POSITION <= 8;
UPDATE cq_item set warghostexp='1536' WHERE player_id='14942916' AND POSITION='12';
