Red mask doesn't drop?

[StanicEnemy]

I have been running Godleaf Foundry dungeon to get red mask but seems like it doesnt drop,is it bug or is there any trick outthere?

Oh it does drop. I farmed it for a good 3hours today and it just finally dropped for me. Ran it about 150-170 times. I almost gave up myself but just kept at it since I already was going for so long. Don't give up. It does drop just longer for some than others. Good luck and happy hunting!
