If you use an Astral Barrier with a standard or greater mana focus you need to charge it with multiple etherium types or the Astral Barrier's etherium consum rate is higher than its etherium charge rate. So if you use a greater mana focus you have to charge the Astral Barrier with dark-,normal- and light etherium or it won't charge fast enough and won't prevent all teleportations succesfully. To change this the charge rate of the Astral Barrier needs to be 3 times greater.
