Fear
'Did I miss it?!' Jake couldn't believe it.
Those were some of the fastest Air Bullets he had ever fired! If this creature moving under snow could avoid that, then his other techniques had no better chance of succeeding unless he took it up a notch. In this blizzard that was sapping his stamina, that was the very scenario he wanted to avoid.
From a Fifth-Ordeal Evolver or even a talented Fourth-Ordeal Evolver, Jake could accept his failure, but not from a Rank 4 or 5 Digestor. It was too soon to meet a Dungeon Boss. They had only just arrived!

"That immediately makes more sense." He chuckled sinisterly. Inwardly, he thought, 'You deserve to die for scaring the shit out of me and making me doubt myself.'
