Believe it or not, in the hands of a trained wizard, this little dinky branch is an extremely dangerous weapon. What some people may not realize, unless they are Harry Potter fans, is that wands are partially sentient. They choose their master as much as they are chosen. The Elder Wand in the Harry Potter series is no exception, but unlike most, it is believed to be the most powerful wand ever created. The power isn’t the only thing that sets the wand apart from other wands. What makes the Elder Wand so different is its lack of loyalty. It only bonds with whichever wizard it feels is the more powerful which is proven by defeating the current master.
Then it moves on and works with the new owner without any disruption in power. This becomes tricky in the series however when Harry Potter becomes the master of the wand through a series of actions that he was not aware of. Voldemort struggled after that to discover who the true master of the wand was after he gained possession of it and killed those he thought had earned its allegiance. It wasn’t till he tried using the wand against its true master did he realize that Harry was the man all along he needed to defeat.
