Elude
Elude: An isolated, static ability that means, "This unit cannot be intercepted." An attacking unit with Elude cannot have the target of its attack changed by a unit with the Intercept ability. The "Elude" Keyword has been renamed to "Precision". Treat any unit with Elude as if it has Precision instead.
