Measure a fight
Enter the total damage and elapsed seconds for the same fight. You can use the stopwatch to measure an interval, then enter the damage you recorded. DPS equals damage divided by seconds. Include downtime if you want encounter DPS.
Compare like with like
Compare the same target, buffs, equipment and interval definition. A short burst window and a full encounter measure different things. Add attempts to the table and export the numeric results as CSV.
What this tool can measure
The result is only as complete as the numbers you enter. No combat-log format is assumed, and there is no automatic game overlay or installable addon here. Inputs and attempts remain in this browser tab.
