Vi's play style of just running straight into the crowd and punching everything that she sees is one that will appeal to a lot of players, especially those up for simple, brutal combat. More importantly, she offers a new champion choice for several different roles, for anyone who might be getting a little bored of their current options.
Vi is available for the standard new champion price. Also available is the Neon Strike Vi skin, giving this femme fatale a bit more femininity. Pick them up together for 1492 RP until the end of the weekend.
