Thokk's eyes bulged as the blood stopped circulating to his head, but he did not surrender. Instead, as bloody blue spittle frothed from his mouth, he leaped into the air and fell down on his back, crashing down heavily on top of Goromir.
Goromir grunted at the impact, but held firm, his body reinforced by accelerated flow. [Flow Accel] did enhance durability, speed, and strength, but because it boosted everything evenly and continuously, it was not nearly as effective as specialized mana applications such as [Guard] or [Dispersal].
Thus, Goromir should have sustained good damage, especially considering Thokk's raw power, but Goromir was trained to take pain.
