Previously I would have said yes, but then Mythic Adventures came out and it then specifically stated that only the Mythic version of the grease spell is flammable.<br/><br/>But you know what... screw that.  Grease is flammable and that's that   ;)<br/><br/>Lighting a tindertwig is a standard action and throwing it into the grease would also be a standard action.  But if you were adjacent to it, you could drop it, which is a free action  ;D<br/><br/><strong>Edit:</strong>BTW guys, don't forget to mention which square you're character is moving into (e.g. moving from A2 to C4) so we have an idea of where everyone is.
