The start was kind of slow with climb being 10 stages before reset... but that all changed after getting the first legendary chest, so if you can stick it out that long the game is definitely worth playing.
- At stage 1000 you can reset boss rewards and dungeon progress and get some very nice perks, this includes the green gems.
- Unique item stacks add to stats much like ranks for heroes, this gives a good reason to continue farming dungeons aside from the additional gems from reset.
- All heroes are unlocked for free through progress which is nice and easy to switch them out as everything can be refunded.
The only thing I don't like is the guardian is seemingly randomly picked at each reset, would like the ability to choose or switch(for like 50 gems maybe) since if you get the same guardian multiple times in a row one team is obviously going to be further than the other.
