After 10 sec, it will release bursts of energy dealing damage equal to 130% of the damage it took, split between all enemies within 8 yards, over 6 sec.
Focusing Crystal is an instant mage talent available at level 100. It allows the mage to create a crystal and, in essence, store damage within it that will then be released to all enemies within range.
