Mob Spell Duration
 

Not sure if this is a classic setup or not.. the Rabies debuff spell cast by crypt mummy in Oasis lasts 50 minutes! Not super damaging, but it seemed so long that I wasn't sure if it was right.

As if that wasn't odd in itself... it also stacks.. I was chased by multiple mummies, whom cast multiple times and the timer is now at 185 minutes and counting.. uh oh :)

It lasting a long ass time is definitely classic though if it's changing durations that is probably a bug.
