Edrik certainly assumed that the creature was a predator, and was very conscious of the fact that it could be right behind him, ready to attack his exposed back. So, while he stumbled over the corpse that he had been lifted away from he stumbled towards an open patch of ground. As his left foot struck the ground he held onto that fear and channeled it into the tip of his cane sword, runes along its length began to glow with a deep blue and bright white. 

He turned himself around as he fell, landing on his ass with his cane pointed in the direction he just came. He was prepared to launch another magic attack, nothing as brutal as the water shield. Rather, if the monster pursued it would likely find that gravity would be turned against it and like a telekinetic push and if stuck would find itself thrown back into the stone crypt it had just dropped from with enough force and strength to crack the crypt wall, though certainly not break it unless it was far more brittle than it appeared.

If not followed than no attack would be forthcoming, rather, Edrik would instead try and scramble to his feet and build his magical power, which would be evident by the brightness and strength of the magic focused on his cane implement, a focus too designed specifically for use with earth magic.
