In my campaign, a wizard who has a staff of the magi was targeted by a chain lightning spell, with the intent that the additional bolts would hit his nearby companions. The wizard opted to use his reaction to absorb the spell with his staff's spell absorption power. His position was that he's the target of the spell, and could absorb it, and there would be no additional bolts at his companions because as the initial target, the spell was absorbed. I re-read the spell and the magic item, and decided to concur with his interpretation. Was I wrong per rules as written? Please advise.
