Does Splash Damage really work?

  • I tried to equip some items with Splash Damage affix but I still don't see any difference even with 52% splash damage (40% from paragon points in Area Damage and 12% from an item). I don't see any flyover white messages when hitting mobs (like 'Frozen', 'Stunned'). How can I tell that Splash Damage really works?
  • An Area/Splash Damage proc is not accompanied by a floating text notification. The damage will be represented in floating damage numbers however, just like any other type of damage.

    If you would really like to test this, equip whatever Splash Damage gear you have, turn on "Display Damage Numbers" (in Gameplay Options) and gather up a small group of monsters. Attack just one of them with a single-target damage skill. When the effect procs you will see damage numbers appear above other monsters within range of your target.
