Dark Elixer cloak of protection
I thought of this idea by playing boom beach.
Maybe you can purchase a cloak that would last a few hours that would increase the health of dark elixer container. The cloak can be purchased by Green gems. Or by a new commodity called Dark Purple Gems. Purple gems can be obtained by fully destroying a dark elixer container of other bases.. and the rate of winning a dark purple gem doesn't have to be 100 percent.
This is analogous to the statues and dark stones in boom beach.. which I love the concept of.
This doesn't change how much dark elixer can be obtained from the dark elixer.. but the rate of how much can be taken out while it's being attacked. Very useful for bases of all sizes and strengths.
Maybe also have a time limit in between of when you can use the cloak.. like you can't cloak de for the next 2 hours from the termination of the previous cloak.
