Before you can edit you need to know how to decode what you are seeing. This is how item binary works:

The skill binaries are made up pretty much the same way but i don't have a guide or anything i can post yet. Once you work out inventory item binary you will see how skills work pretty quick. Just make a basic character with just the starting skills and check the binary. Level a skill up, check the binary again.
Some SQL for your gamedb:
Code:
select data,convert(varchar(max),data) from cabal_skilllist_table where characteridx=<insert charidx here>
The data field in cabal_skilllist_table is a varbinary(512) if you want to convert it back for an update statement.
