I am looking for other experiences. Here was mine:
Background: I started playing about 5-6 months ago. I've enjoyed the game, although the opaque gambling features can be frustrating and lure players into increased spending with uncertain or disappointing results. Nevertheless, from an investment of around $250 USD over that time on Nemesis cell packs I have four dungeon worthy Nemesis monsters: Llum the Magical Matriarch, Xiron the Emerald, Samael the Plague Carrier, and Warthak the Mountainsplitter. Each has a combination of gold and purple relics and L6-10 runes, with four L10 runes between the group, primarily speed. All are L100 - while I've spent another $100 or so on enough elementium to get two to rank 3, I've kept them at L100 so that they don't outpace the bulk of my monsters and make level based weekly dungeons impossible. Clearly that will pace how far one can get in the dungeon.
So with that background, I opted to take Llum, Xiron, and Samael into the dungeon. Not the highest damage output but the team has resurrect capabilities, redundancy in ability to remove negative effects, heal, and control. It should be a risk averse, slow and steady team.
The experience: In the first dungeon, Xiron goes first and Mr Scratch second. I go for control dice as likely the best control option even post nerf. It misses on all three enemies. Next, Scratch possesses my team and it lands on Samael. He does the least impactful move to me on his next turn - death moratorium - but it will be his last move. Following other control moves by the dungeon team, he will be dead before any of my monsters get another turn. Xiron will have a chance to cast total exhaustion once before he is out, and Llum will not see the light of day until she has no allies left. Total wins: 0.Total damage inflicted: 0. As it is a survival dungeon, there are not enough monsters to field another go...unless I spend more money on the monsters currently on sale.
So for an investment of $250 on chests alone, that was my experience with the exclusive Nemesis Survival dungeon content. I expect other experiences differed, but I am interested in hearing about them to get a more full perspective. Please share your experiences.
