Riot Games has revealed a new champion for the upcoming Legends of Runeterra expansion: Sejuani. The Freljordian warrior rides into the digital card game on her trusted companion, introducing four other new cards and a brand new keyword in 'Vulnerable'.

When a unit receives the Vulnerable effect, it can be forced into battle by the enemy. It's best compared to a very narrowed-down version of Challenge, as you can only target one unit with it. However, for Sejuani specifically this doesn't matter much. Her second on-play effect is that she applies Frostbite to the same enemy she makes Vulnerable, setting that unit's attack to zero and giving Sejuani a free trade.

Sejuani also boasts the Overwhelm effect, which plays into her requirement to level up. When you have dealt damage to the enemy Nexus in five separate rounds in a game, Sejuani transforms into a Frostbiting menace. Every round, the first time you deal damage to the enemy Nexus, Sejuani Frostbites all enemies on board. Talk about a stone-cold heart.

Alongside Sejuani, Riot Games has revealed four other cards coming to Legends of Runeterra in the next expansion. Fury of the North is a straightforward buff card, Ruthless Raider is quick aggression, and Ember Maiden is a cheap Area of Effect card capable of dealing with small and severely weakened enemies. Lastly, Stormclaw Ursine is a strong Overwhelm unit pushing the Freljord in an aggressive direction by granting all units with five or more attack power the Overwhelm keyword too.

Legends of Runeterra is ramping up towards its full release later this month, on April 30. The new, yet-to-be-named expansion is supposed to go live on April 28. Earlier this week Riot Games already revealed another new champion joining the lineup: Quinn.
