Last Z hero Level Swap moves progress, but star limits still matter
An in-game rules screen from the dinosaur-themed season distinguishes level swaps from skill transfers; availability depends on server progress.

In the dinosaur-themed season of Last Z: Survival Shooter, Level Swap gives hero development another route: two heroes can exchange levels instead of starting the work from scratch. Player site LastZ.GG has published an in-game rules screen from what it calls the Season 3 Dinosaur Origin. Season numbering and progression differ between servers, so that screen does not establish that every server has the feature.

The displayed rules say a swap consumes a Level Swapper and fully exchanges the two hero levels. The distinction is useful: this is an exchange, not a one-way copy. When one hero takes the other’s level, the second receives the first hero’s former level. The timer in the image belongs to that account at the time of capture, not to every server.
Skill levels have extra conditions. Heroes of the same quality can exchange levels in matching skill slots, with each skill individually selectable; between different qualities only hero levels move, not skill levels. A skill also locks temporarily if the new hero level falls below its unlock requirement, and reactivates when that requirement is met.
Star limits matter too. The in-game screen says a skill is capped at the level allowed by the receiving hero’s stars, with no refund of excess skill books. Another summary on the same site says excess books are refunded, so the two descriptions conflict. This report follows the displayed game rules and leaves the current confirmation screen on each account as the final reference.
The feature offers a way to redistribute existing hero levels, but it does not promise that every skill investment moves as expected. Server season, the swap item, star levels and the current in-game confirmation are more relevant than a countdown from someone else’s screenshot. That applies to players in Indonesia, Thailand and elsewhere.
