Baneful Smite has very long range, which a player should learn to utilize to the best of his ability. It should be used against small groups of enemies (2-6). A player may improve it with the Chain mod to strike 2 targets in close proximity for full damage.
Can also be used as "debuff" strategy by choosing the mods Laggard and Confuse, which will also effect bosses. Bosses will have a lesser chance of hitting a player successfully.
