I have one question about mysql working.
I created in characters table 15 my custom fields, like example how much mob killed player etc.
This can effect lags, stability etc.?
Better create example another custom table where will be custom info?

Is matter how much often you called it do you cache it somewhere and stuff like that. If not sure better use separate table.
