If you can get Air in there as well, could add Mass Flight.

And Maybe toss in Body Ethereal? Not sure what the relative benefits of delaying the explosions might be, though if the undeads mass up around the slaves nicely.....

Body Ethereal won't spread to all the slaves because it's not caster-only. For the same reason you might as well choose Flight over Mass Flight (all the slaves get it automatically when a master casts it).

To fight chain reactions, throw in a Stoneskin or Ironskin. Phoenix Pyre is actually quite bad at killing anything armored.
