I really love the concept of the Trove of the Thunder King solo scenario. In fact, I almost like the idea & the scenario itself more than the actual rewards. Really, it's just gold, Elder Charms I don't need, and rep things I also don't need. I mean sure, they're nice, but I'd honestly give those up just to be able to run this thing repeatedly and perfect my route.
Anyway, I took a video of my first one, partially to record the results and also to examine/help plan out future runs. I decided to stick completely to the first room + the hallway leading to room #2.
It's definitely not the most efficient run - there was some learning going on as I ran around, obviously - but maybe you'll see nooks or crannies that you didn't know existed! Next time I'll definitely try to do a little less exploring/backtracking. Also, use Pally bubble / Hand of Freedom more to just ignore the Lightning trap's effects.
The biggest thing I learned from this run? You can leap on unopened chests to reach higher ledges, and TRY NOT TO BACKTRACK SO MUCH.
Total haul: 31 small chests, 2 big chests, 1 gold chest.
(no extra keys found - you get to open one gold chest at the end no matter what.)
The # of chests is the important thing, since what you get is all random anyway.
Overall, I ended up with:
11x Mote of Harmony
10x Tattered Historical Parchments
8x Elder Charm of Good Fortune
1x Shado-Pan Assault Insignia
I found two more keys this week, but I haven't gone in for a second run yet! I'm almost capped on Elder Charms and I feel like getting more would just be wasting them...but at this point, I might just say screw it and not even worry about them, since Fabulor really doesn't need anything that they can be used on.
