The Whelps were not a threat to any of them, but they couldn't ignore them either. It took three normal hits before dying. A swarm of them could really become annoying. A ten-player dungeon did not make any distinctions between a ten-player team or a seven-player team.
A single wave of Grimhorn Whelps had over 14 to 16 such beasts. Fortunately, both Bella and Prince could handle four each. When one of them wandered around, Kai quickly one-shotted the Whelp. Zayden, Jor, and Mimi each handled three, with occasional help from Sherry, who killed one or two or helped injure them.
