Anyone who has played DDO for any length of time knows that any enemy capable of tripping you numbers among the most dangerous of its level by default. But did you know that they can potentially render your entire computer nonfunctional, such that it requires a full format and reinstall or worse?
And you thought being unable to act in game was bad...
(No, I don't really think Jariliths are to blame for this, but it did happen while playing DDO, and I'm trying to be funny even though I feel like being anything but.)
