Revealence
In the official guide from nintendo power for diamond/pearl (the old one) it has dark void in the list of moves that cause sleep condition and deal no damage but does not have it listed in the full list of moves. Atomix26 01:19, 4 November 2008 (UTC)
Unclear description
In a double battle, Dark Void will hit both foes, and the accuracy of said move is dependent upon the Pokémon that is targeted.
What does that mean specifically?
That it may fail on an opponent that is already asleep, affected by another status ailment or under a Substitute, but that the move may hit the second opponent regardless of failing on the first?
That it may fail on certain Pokémon due to type?
That it may fail on some species of Pokémon? Looce 12:22, 22 January 2010 (UTC)
