I think the new map is kind of waste of time.
The energy cost for a run cost to much and they are easy to kill. 15 energy and 25 for a little bit of xp
The xp gain isnt that great and the most chest that u can get is 4 with boss chest.
why do that jewel when i can do a normal map with 1.5X the drop rate and get 9 card and level my card better and the xp is still good
with less energy cost too.only 10- 16 energy use and 9 chest.
Maybe if those jewel card give a small chance of skill lvl up or more increase in xp or even more chest drop THEN maybe it is worth it but
i dont think that the jewel run is worth it with only 1 hour of event only
