Wall of Ice?

[Gwarthkam]

Does the Reflex save to 'disrupt the spell' replace the old Reflex save to 'avoid getting trapped'?
For instance: if I try to trap someone in a hemisphere, do they get both the 'disruption' save and the 'escape' save?

Yes, the 3.5 "disrupt" save replaces the 3.0 "escape" save.

If you try to trap someone in a hemisphere they may get a "disrupt" save. There is no "escape" save.

Note that a creature only gets to make a "disrupt" save if they're adjacent to the wall when it is cast. A medium creature in the center of a 10' or larger hemisphere is outta luck. (no save. at all.)
