This move would cast similar to flick, only looking slightly more down at the ground and with the top hand not being upside down. Upon casting, this move would send out a crack from the player’s feet the would move forward until it hits the end of the ring (or a fixed distance OR a structure of player if it is too strong.) (Just like in avatar when earthbenders make a sort of line between them and the earth they are about to move.) You see where this is going? When you have a tunnel going, structures you spawn will appear at the end of the tunnel. Also maybe poses like straight and explode could be used at the end of the tunnel as if the player was standing there if no other objet would be affected where the player is actually standing. This could be pretty op (especially if you could spawn structures in people to hurt them. As much as it would look like avatar and would be sick, I think it shouldnt work like that.) but it would be a super interesting move in my opinion. You could make explode setups of predict your opponent’s movement to make them run into a wall, abd the move has built-in synergy with litteraly everything in the game so it wouldn’t feel out of place and neeche since it litteraly requires the usage of our well known and loved moves to do anything. Sure it would need sone tuning and attention from the devs, but if they are open to adding some new moves, I think this idea isnt one to miss. I really thinl there will never be something more exciting in rumble than a new move being added.

Finaly Ill just add that of course there could be shiftstone(s) related to this move, like making it go faster, further, under structures if it doesnt already or even curve a little (like in the direction of the hand on top) would be super cool and a nice way to flesh out and make the move feel even more included in the game upon release.

Thank you for reading this far, have a good day.
