I was creeping around a greater vault at 1800 ft, as you do, and noticed a greater titan. Having killed a lesser titan with ease, i decided that he probably wasn't harder... well, a few rounds later, thanks to my error in judgement, i was a dirty smear on the ground.
I made another mistake, i snuck back towards the GV as a ghost, and by the time jube arrived for the rescue, the titan had squished all of my gear as well, except for a couple of items... i spent a fair bit to replace everything i lost.

But with my new gear, i actually have more resists than before, which is kinda cool.
