The better version of this is database normalization which implies you make for every value you need a column. Does the data is duplicate(eg: weapon1 weapon2 etc) then make a dedicated table for it with at least 2 column (ownerid and weapon) and every row will mean that x owner has y weapon which will mean you need join and forgein keys
