Orb of Infinite Depth is a Legendary Source for the Wizard in Diablo III, added in patch 2.4.0. It requires character level 70 to drop.

The unique affix applies once per cast, provided that cast hits an enemy. Both damage and damage reduction are multiplicative to other similar effects. Note that with Chain Reaction rune, each cast counts as 3 different hits, so it applies 3 stacks, provided all of them hit an enemy.

Number of stacks (and duration) will be displayed on the skill icon of Explosive Blast.

“There were three — Borax the Barbarian, Patel the wizard, and Zatheria the demon hunter. They drew on their unwavering bond to each other to keep from falling to the twisted lord and his minions. Tired, cornered, and near death, they readied themselves for their final assault.” — Chronicles of the North
