It was a pretty interesting book, no?
It's much easier than Sanctum of Destruction. Majority of the monsters are fat and can get pushed, which is basically Dive Bomb fodder for my xbow.
It's also nice to be a Battle Mage here so you can deep impact the mobs. The boss summons a lot.
I actually got stuck as a golem once (at boss), but I couldn't figure out how to get out of it. It's either timed, or I have to wait until the golem dies. If it's timed, then that's a pretty long timer....
In general, I wasn't close enough to aggro any monsters, so I stayed at full life for pretty much the entire run. I'm so glad none of the bosses have a spammy shadow ball that can snipe people.
The necklace looks delicious, the crest, not so much.
Apparently, you CAN run both Hero dungeons if you finish one fast enough. I went in to test. (It also says in the Hero bullion shop that each dungeon has their own counter. I just wish the timing didn't overlap..)
