如果伤害地形不行那么其实支配也可以……
slide进入hindering terrain也是有save的，支配那个说的也是hindering terrain
Hindering Terrain: Forced movement can force
targets into hindering terrain (page 61). Targets
forced into hindering terrain receive a saving throw
immediately before entering the unsafe square they
are forced into. Success leaves the target prone at
the edge of the square before entering the unsafe
square.
If the power that forced the target to move allows
the creature that used the power to follow the target
into the square that the target would have left, the
creature can’t enter the square where the target has
fallen prone.
If forced movement pushes a Large or larger creature
over an edge, the creature doesn’t fall until its
entire space is over the edge. On the creature’s next
turn, it must either move to a space it can occupy or
use a move action to squeeze into the smaller space
at the edge of the precipice.
A DM can allow a power that pushes a target
more than 1 square to carry the target completely
over hindering terrain.
