Can fictional abilities of a character be protected by copyright?
<p>Some examples of abilities from games:</p>
<ul>
<li>In Dota 2, the hero Queen of Pain has a ability/skill called <em>Scream of Pain</em>. It is essentially a kind of &quot;magical&quot; scream that damages nearby enemies.</li>
<li>In the Warcraft universe the so called &quot;night elves&quot; have an ability called <em>shadowmeld</em> that makes them invisible, leaving only the shadows.</li>
</ul>
<p>Are abilities like these protected by copyright? Also, there are any court cases regarding this?</p>

That makes those two powers older than</p>
<h2>You can not have a copyright on concepts, facts, or ideas.</h2>
<p>Facts are not copyrightable, which was decided LONG ago over <em>Feist v Rural.</em> Neither can you copyright concepts or ideas. You won't get a claim on the concept of a damaging scream or turning into shadow.
