<p>According to the <a href="http://dragonball.wikia.com/wiki/Evil_Containment_Wave" rel="nofollow noreferrer">wiki</a>, the move requires so much of the user's life force to perform that those who use it are likely to die soon afterward, despite the success of the technique. The drawbacks of the technique can be negated if one posses enough power to use it without dying.</p>
