Mantids process poison rapidly, have lightly armored necks, and are disrupted by loud noises despite common antidote protection.
CrawlCon attendees say poison acts on mantids almost three times faster than on most species. In practice, Vrah carries an antidote ring and has gained cloud-poison immunity, so a useful toxin would need to be incurable or kill within about five seconds after a blade strike.
A mantid's neck is its least-armored body section. Other hunters use loud alarm traps because noise hurts mantids and can keep them from swooping down to steal crawler kills.
The combined weaknesses give Carl concrete targets and control tools for the coming Dark Hive fight.
