Imagine a party of PCs exploring a dungeon inside a volcano. After a climactic confrontation with the Big Bad, the volcano begins to erupt, and the PCs must flee for their lives. Unfortunately, one of the PCs -- Tarly Target -- is badly injured and can barely walk. Working together to carry Target, the PCs race toward the volcano's mouth. Just as freedom nears, a sudden quake tears open the path before them, creating a 15-foot chasm that begins filling with molten lava. There's no way Target can make the jump.
As a bonus action, you can try to telekinetically shove one creature you can see within 30 feet of you. When you do so, roll your Psionic Talent die, and the target must succeed on a Strength saving throw (DC 8 + your proficiency bonus + the ability modifier of the score increased by this feat) or be moved toward you or away from you a number of feet equal to 5 times the number you rolled. A creature can willingly fail this save.
Assuming Psion could roll a 3 or greater on his Psionic Talent Die, sufficient to move Target the full 15 feet required to clear the chasm, is this a viable use of the feat? Must Target remain in contact with the ground the entire time he's being moved by the shove, such that he'd immediately plunge to his doom once moved over the chasm? Or can the shove actually propel him through the air to the other side?
For completeness's sake, I note the following:
- The normal shove action (PHB p. 195-196) only moves a creature a maximum of 5 feet, so it does not offer much guidance here.
- The telekinesis spell (PHB p. 280-281) can move a creature, but the move is not characterized as a shove and explicitly can hold the target in mid-air, so it is not helpful here either.
