Varus Ability (LoL): Chain of Corruption

Varus flings out a tendril of corruption, rooting the first champion hit for 2 seconds and dealing 150 / 250 / 350 (+100% of ability power) magic damage. Rooted enemies gain max blight stacks over the duration. The corruption spreads from its target to uninfected enemy champions. If it reaches them, they take the same damage and root.
