The cinematic depicts a modern-day adaptation of Ezreal discovering the latent power of his Zodiac Relic before being attacked by the villainous Lissandra. The cinematic was likely meant to launch in tandem with the upcoming skin line, but the German League of Legends account posted it early.
In the Porcelain Protectors cinematic, Ezreal assembles an ancient porcelain vase while studying in a building inspired by feudal Japanese architecture. Ezreal puts the last piece into place before turning back to his laptop, presumably to continue studying the Zodiac Relics given that his laptop displays the remains of a dig site with portions of mythical porcelain. As he turns away, the vase shimmers with magical energy and suddenly the blue snake depicted on its side comes to life.
Ezreal has somehow released Lissandra and her snake spirit companion back from some long-lost era. Lissandra chases Ezreal across the room, and he uses another Zodiac Relic to summon a spectral tiger who leaps to his defense. He can’t do it a second time and has to be saved by Lux, who enters dramatically through the skylight. Lux and Ezreal combine their spirits’ powers to repel Lissandra, who escapes through the wall of the building.
The Porcelain Protectors skin line isn’t the first to get a cinematic, with Riot occasionally breaking out their top-notch animation departments and partners to promote new cosmetics. Porcelain Protectors being tied into Riot’s Lunar Revel for the lunar new year has lent them more space to have flashy additions like the custom Porcelain Protectors cinematic. The Porcelain Protectors skin line will go live with the rest of the Lunar Revel event, including the Lunar Legend Festival for Teamfight Tactics.
