Strategy and Uses

 * Typically, Aftershock is used in combination with knockdown skills to maximise its damage, especially among KD/AS characters.
 * Combines well with Whirlwind.
 * Some Earth elementalists use the combination Earthquake/Aftershock to deal extreme area damage, but the long casting time of Earthquake can make this difficult, as the targets may move away before the Earthquake completes. Casting Ward Against Foes or Frozen Burst before casting Earthquake helps to prevent this.
 * Gale is an excellent complement to this spell for an Elementalist because it knocks down foes for a 3 full seconds and does not require more than 5 points in Air Magic.
 * Shield of Judgement is also a great companion skill to this, as it knocks down foes everytime they attack.
 * For a warrior, this combines well with Earth Shaker, as it is the only skill in the game that knocks down all adjacent foes simultaniously almost without failure.
