So far, to me, it's not worth it. Only thing I like from it is partial energy refill and gems. Have done the quest several times already and only yesterday did I get a dark cave formation. No trees or animals : (
I usually get earth whisps, coins, energy, gems, silver ore, royal beams or blocks, super glue, and/or those beams with the numbers on them. So, in total for me, I consider it a waste of energy...plus need earth whisps to expand and takes an hr to craft one :/....5 hrs just to get earth whips....everyday most of my energy is used just to fulfill quest requirements : (
I have a unicorn state and the lion? Statue, but those both came from a less expensive quest
