This creature appears as a giant beetle with a dark green carapace and wing-covers. Its body is covered in leaves and sticks. Its mandibles are silver and its legs are black.
Giant Deathwatch Beetle CR 6
Speed 30 ft.
Melee bite +11 (2d6+7)
Special Attacks death rattle
Once every 1d4 rounds as a standard action, a death watch beetle can vibrate its carapace to produce a clicking noise that sets up vibrations in all creatures within 30 feet. Creatures that fail a DC 17 Fortitude save take 3d6 damage. Since the effect stems from the vibrations set up in a victim’s body and not from the clicking noise itself, silence offers no protection against this attack. Likewise, a creature that cannot hear can still be affected. A successful save renders the target immune to that death watch beetle’s death rattle for 24 hours. The save DC is Constitution-based.
Environment temperate forests
The death watch beetle makes its lair in forests and uses a mixture of saliva and earth to stick rubbish (leaves and twigs, for instance) to itself in order to attack by surprise.
The death watch beetle begins combat using its death rattle ability. Any creatures that survive are bitten by the beetle’s mandibles and devoured.
