First thing you need to to is gather the character id from cq_user. Then open your cq_item and find the item you're looking for where the player_id is equal to the cq_user.id
Once you have found the item you want to edit then you will change the following columns
magic3 <-- this controls the +'s on the item like +1 +2 +3 +4....
warghostexp <--- this controls the soul 1024 is fsoul 8 I believe
eudemon_attack1 <--
eudemon_attack2 <-- These control the elements on the item.
eudemon_attack3 <--
eudemon_attack4 <--
Remember you can only do this if the checksums on your server files are removed. I'm pretty sure most of the released files here have it taken out.
