Jarvan IV extends his lance, dealing physical damage and lowering the Armor of enemies in its path. Additionally, this will pull Jarvan to his Demacian Standard, knocking up enemies in his path.
W - Golden Aegis
Jarvan IV calls upon the ancient kings of Demacia to shield him from harm and slow surrounding enemies.

Jarvan IV carries the pride of Demacia, passively granting him bonus Attack Speed. Activating Demacian Standard allows Jarvan IV to place a Demacian flag that deals magic damage on impact and grants Attack Speed to nearby allied champions.
R - Cataclysm
Jarvan IV heroically leaps into battle at a target with such force that he terraforms the surrounding area to create an arena around them. Nearby enemies are damaged at the moment of impact.
