I do not know what happened to the damage has been very low So that the crystal has no value I would stop developing I am a level 52 player and have a Crystal Attack 7,6,3

I even kill monsters less than my level with difficulty Why became 1, 2 and 10 instead of 7 thousand and 10 thousand How to raise the damage Do level 7 of the crystal makes it easier to kill the monsters or crystal is not useful in this update
