A question came up last night in my game. One of the players is playing a ShadowDancer and used the Shadow Jump ability. The question is, does useing this ability invoke an attack of opportunity?
IIRC Shadow jump is a supernatural ability. And supernatural abilities do not inherently provoke attacks of opportunity. So as long as I am right about the supernatural ability part, then it does not.
Obviously you're thinking as we did, but the description for shadow jump states: "At 4th level, the shadowdancer gains the ability to travel between shadows as if by means of a dimension door spell." This lead us to question whether it's a spell like ability (which invokes attacks of opportunity), or a supernatural ability (which does not).
Hmmmm - it's really hard to say. It does seem to be more a spell-like ability (by comparing it to dimension door), but it's isn't dimension door (as it is limited to shadows). I'd probably rule it as a supernatural ability as I see it as an extension of Hide In Plain Sight which is a supernatural ability.
