OH MY GOSH
So I was in the Nether looking for Quartz. Got a bunch of stacks of the stuff, was about to mine another deposit when suddenly BAM! Ghast blast and I'm flying straight into a huge pool of lava.
Had full health + fire resistance on one of my pieces of armor, so thankfully, I was able to dig my way out of the lava and survive the burn.
MAN! That was close.
