Time Stop and Sovereign Glue

[Rkhet]

Yep. So it doesn't set until after time starts.

I just got another idea. Time Stop just when someone's taking a step. Apply glue on their foot. They probably won't notice, and when they put their foot down again, distract them enough so that they won't take another step. Six seconds later, the glue sets and the BBEG is nailed to the floor.

Many people undersestimate the usefulness of the Ready action in conjunction with TS. For example:

TS round 1: Polymorph Any Object to open big hole in floor under BBEG (as suggested by previous poster).
TS round 2: Wall of Iron next to BBEG.
TS round 3: Ready action to push wall over as soon as TS ends.

TS ends, BBEG falls in hole, wall of iron falls (pushing BBEG into hole if he flying/levitating), BBEG trapped. (Of course, many BBEG's at this level will have teleport capability, but still...)


Now, I'm sure that a dozen people will flock around and prove that by the RAW this won't work (this is the Rules forum, after all), but the point is that just because TS doesn't allow certain actions doesn't mean you can't be ready to do those things the very moment TS ends.
