The opponent&#39;s evasion is reduced 1 stage (4/3 or x1.3). Defog also removes the effects of the following moves: <a href="http://pldh.net/dex/move/lightscreen" class="linksred">Light Screen</a>, <a href="http://pldh.net/dex/move/mist" class="linksred">Mist</a> and <a href="http://pldh.net/dex/move/reflect" class="linksred">Reflect</a>. Defog will also remove any Spikes setup by the user if the target of Defog is the opponent. If the target of Defog would be a teammate in a double battle any Spikes are removed from the user&#39;s side of the field instead of the opponent&#39;s side.
