Iliar draws and fires his crossbow in one swift motion, hoping to catch the villain before he hurts Verakka any further. The bolt flies true, but the dark elf swats it aside with a lightning fast arm movement.
Titus runs into the shower of sparks and touches Krug, whose sinews and biceps bulge with new strength. Titus avoids being blinded by the sparks, but finds that a strange red gas begins appearing in the air all around him. Coughing on the fumes, he finds some of his own strength departing.
Krug gets a small whiff before advancing on the drow, but still feels stronger than normal. As Krug gets within ten feet, some of the sparkling powder gets in the elf's eyes, clearly affecting his vision. Nevertheless he still possesses enough sense to dodge Krug's axe stroke.
Grim also fires his crossbow at the stranger and misses.
The dark elf steps away from Krug and calls on his race's innate magics, plunging the three melee combatants into darkness. Verakka recovers from stunning in time to take an attack of opportunity, but fails to stop the elf.
