Drisquar carefully fires six arrows at one of the Gugs before it reaches the top of the wall.
Attack rolls and reactions:
The creature's hide is tough, and Drisquar's arrows barely seem to wound it, although three hit hard enough to draw a quiet growl from the creature. The sixth and final arrow, fired as the Gug nears the top of the wall, manages to hit a nerve in one of its four hands—the creature shudders, pulls back from the stone and, losing its footing, tumbles back into the chasm.
Another Gug reaches out to catch it, but narrowly misses its arms, and it falls, disappearing from sight. Five seconds later, there is a sickening crunch from far below, followed by a series of four or five howls from different points below you.
