The pra'eda before you stands on two legs, but the golden eyes that glare from either side of its fanged, canine snout and its coat of grizzled fur make it difficult to determine whether it is more human or wolf in nature. A stench of blood and rotting flesh emanates from its fanged jaws, and its rough, tattered clothing is stained with dirt and gore.
A good hunting strategy for avoiding a pra'eda's maelstrom is to move into another room when it is cast upon you, and then hide. As long as the pra'eda does not follow you into that room the energy maelstrom will dissipate on its next round of action. Then you can move back into the room with the pra'eda to continue killing it.
Praeda (no apostrophe) is a Latin noun meaning "spoils of war" or "prey." The Latin verb praedor (meaning "to acquire loot," "to pillage" or "to ravage") comes from praeda and gave rise to the word praedator, from which we get the word "predator."
