Lore
Prince Jarvan, scion of the Lightshield dynasty, is heir apparent to the throne of Demacia. Raised to be a paragon of his nation's greatest virtues, he is forced to balance the heavy expectations placed upon him with his own desire to fight on the front lines. Jarvan inspires his troops with his fearsome courage and selfless determination, raising his family's colors high and revealing his true strength as a future leader of his people.
Ally Tips

You can use the Dragon Strike / Demacian Standard combo to get out of your own Cataclysm arenas.

Split your basic attacks on different champions at the beginning of fights to maximize damage.

Use Demacian Standard as a scouting tool when worried about incoming enemies.

Enemy Tips

Keep out of the path between Jarvan IV and his Demacian Standard to avoid being knocked up in the air.

Cataclysm's terrain is a frightening force to fight against, but movement abilities can go through it.
