If I used Akshan to attach an equipment and had Lucian take the equipment when played, do I give equipment back?

When you use Akshan to steal an equipment and then move it to another unit (like Lucian) using a Weaponmaster effect, you do not automatically "give it back" the moment Akshan leaves play.

According to RiftJudge FAQ #694, here is how the interaction works:

1. Control: While Akshan is in play, you control the stolen equipment.
2. Moving the Equipment: You can use a Weaponmaster effect to move that equipment to another unit you control (like Lucian).
3. When Akshan Leaves Play: The equipment remains attached to Lucian even after Akshan leaves play. However, once Akshan leaves, your control effect ends, and control of the equipment returns to its original owner.
4. Getting it Back: Because the original owner now controls the equipment again, they can use their own effects (such as their own Weaponmaster ability) to move it back to one of their units.

Summary: The equipment does not immediately jump off Lucian or return to the opponent's hand when Akshan leaves; it stays on Lucian until the opponent actively moves it or Lucian leaves the board. Once Akshan is gone, the opponent regains control and can take it back at their convenience.
