(OOC: Oh right--no Grace yet

Well the save DC isn't so high, so let's see

I'm assuming a full-round action)
*Baeleth slams into the crates on which the summoner is standing and pushes hard, and they begin to fall.*
"Wh...damn!" the summoner yelps, as he falls to the ground hard and is quickly covered by crates.
*Besides the summoner, the wolf is also trapped underneath crates, but Baeleth, the rat, and the badger only take minor damage.*
*The angry animals scramble out of the crates, but it is all they can do to move up near Baeleth, not attack.*
(OOC: Summoner takes 14 Damage, then 5 Damage.
Wolf takes 6 Damage
Badger takes 2 Damage and is enraged
Rat takes 1 Damage
Baeleth takes 1 Damage, total 8
Extricating oneself from the crates is only a move action, since he isn't actually trapped. It is still difficult terrain, so each square counts double and no five-foot steps. Still, the enemies are right next to him now.)
