Can we find solution for this system?

[JFAMAP]

Hello everyone. We have a hero that can grab the enemy and jumps behind with the grabbed unit. But the problem is, both of the target and caster can be stucked if they land to cliffed areas, water or between trees. Can we find any solution for that?

Update: Currently we are thinking making this spell cast range and throw range exact the same. If i will do that, both target and caster moves to the location of caster. But feel free to suggest anything that can help.

Update 2: Yes, my first update probably best solution.
