This vision card reduces the energy needed to farm Job points (JP). Free to play players may pass on this card since they can chose a friend unit that has this card equipped and gain the JP boost.
A notable mention is the JP Reward Quest event, where bringing a unit equipped with the card can boost your JP earned to 750 or up to 1000 if you have the maxed card equipped and bring a friend unit also equipped with this card.
When this Vision card is obtained, it's 4★ and Lv.1.

If you embark JP Reward Quest with both your own and your friend's Job Crystal vision card (max Lv.), you'll gain 500 + 500 = 1,000 JPs (equivalent to farming 30+ red crystals for each of your units)
The first comment is incorrect. Companion party abilities do stack with your own party abilities. So yes, the effect is increased from owning the card and having a companion that has the same card, as well.
How does one awaken this vision card if it's only something that one can purchase on the special shop? Please advise.
