Is there anything I can swap to improve?

drop the flame serg. ring and use another rubellite +1. change belt to veteran's or flame sergeant's belt. imo

I read through these threads and have to ask.
Why drop the flame serg ring for a rubellite +1?
As this person is wearing 3 Flame items they get the bonus which is a grand total of 20 attack. STR +18 from the rubellite would only give 9 attack bonus. Is there something I am missing that would require dropping 20 attack for 18 str?
