It's deceptively difficult to bait a Diablos into grazing so you can snap a picture of it, especially when you're a dumbass like me
Looks like it's time to bust out the ol' exhaust phial swaxe 🙄
Like a fucking fool I panicked that the quest timer was getting a little close for comfort so I went and attacked a Diablos without realizing it'd finally walked over to the cactus patch where they graze
I'm going to fucking scream, I didn't even get enough of the event quest's special reward to make the layered armor (not that it was even layered armor I particularly wanted), so that was basically a waste of ~50 minutes
