I haven't seen any damage parsers posted on many forums as of late so I thought I'd post one that I made myself. You do not need a log reader for this however as it has been injected directly into the program. FFXI will run slower while this is running because the program has to first make the log files into a readable format and then read them once again to find the damage X-X. If you have a fast computer it shouldn't be a problem though. It also reports how much damage each person in the party has taken as well as their damage AS LONG AS THE CHAT FILTERS ARE OFF. I can't tell you how many n00bs I've had email me telling me it's not working when their chat filters were on.
