It seems my previous report (linked below) was COMPLETELY WRONG. I've tested the real damage while under both Berserk status and Normal status and the DEF, MDEF and FLEE are reduced as they are supposed to. So please revert the changes of the earlier report. The status on the status window of iRO was just a visual thing. My apologies and thank you.
Conclusion from tests on iRO:
Normal Attack (Normal Status) - 17 Damage
Normal Attack (Berserked) - 245 Damage (DEF reduced)
Holy Light (Normal) - 87 Damage
Holy Light (Berserked) - 315 Damage (MDEF reduced)
I had tested the flee part as well but there's just no way to show it with a SS. But it is confirmed that it is lowered by half.
