How to get the best use out of the Hyper-Dimensional Anchor's and the Xecti Ensconcing Field's, also can u use them on a planet once u have maxed the passive cloaking with Interspacial Fold Generator's and magnetosphere chargers?

Yes you can use them past the cap of fold generators and chargers, the best use for them is to use them on a Mega Colossal 22x arti world to get the cloak to about 22k+. There are many guides on how to get there effectively on the forums, it shouldn't take long to find one with the search function.

Thnx Epic
