While sourcing the gems necessary to conjure the elementals is a challenge itself, the bigger concern is whether there is still enough loose mana in Shen'dralas to create them. With this heart, we can confirm once and for all whether we need to begin researching other means of defense. For you, the task is simple. Simply toss this gem into one of those unstable rifts. If we're lucky, you'll have a fight on your hands. Don't feel compelled to hold back, if it works once, it will work again.
