Area of Effect (also known as AoE) is a term which refers to a multi-tile effect, spell, or attack that targets more than one tile simultaniously. In order to balance this effect, as the damage area is spread out it loses some of its potency, specifically 10% for each square out from the center targeted tile (see images below). It should be noted that this effect is an average, as the damage appears to be rerolled per each monster, so it is not uncommon to to have a monster far from the center take more damage than the monster in the middle.
Examples include Revitalizing Word (level 5)
A 41 tile "circle" is the area affected with the center tile as the target area.
Examples Include: Manifold Bramble
Area of Effect (AoE) skills affect a given area of the playfield, and not any one specific target; any target inside of the area will be affected by the skill. The affected area generally does not move over time, so players can move away to avoid negative effects or closer to benefit from positive effects. Area of effect skills affect all valid targets within the horizontal radius regardless of barriers or altitude.
Most AoEs require a target; however, some will take effect around the caster. These are called PBAoEs—point-blank area of effect.

As stated above, computer-controlled creatures will flee upon being inflicted with such pulsing damage after two to three seconds. However, if the creature is effectively body-blocked by players or any other mobs (not including spirits), it will be mind-frozen trying to reach its previous target or skill use location: hence a melee or touch-range Boss could be defeated easily, unable to attack or use any offensive abilities.
