Undead mask too rare?

[octavos]

Permanent drops should be rare.
Limited time drops should be attainable in, let's say, 10 hours of investment.
The rarity of this drop I feel is bad form.

Poor spirited.

I don't mind farming an x ray for months, but if I don't find this before the event concludes, after 80k + kills, I will freak.

Sadwoof

Amen!
