Active: Varus flings out a tendril of corruption that infects the first enemy champion hit, dealing magic damage and snaring them for 2 seconds.
The corruption then attempts to spread towards enemy champions within 550 range, applying the same damage and snare if they stay within 600 range of the infected champion for 2 seconds. The corruption will continue to spread until there are no further targets in range, but each champion may only be infected once per cast.
