One of the most effective tricks with the weapon is that any enemy, short of a Hell Knight, which launches a fireball is immediately killed if hit by its own projectile, making it very easy to kill legions of Imps and Vulgars without firing a single bullet. It is also very easy to simply intercept and then toss fireballs on other enemies, though since it can only hold one fireball at a time and takes a short period to recharge, groups of enemies can quickly overwhelm you. And unfortunately, this fighting method is ineffective with Z-Secs, and much trickier with Revenants due to their launching two rockets at the player in an attack, since the Grabber can only catch one at a time.
