Description
Ambush Pit (Ex) A giant emperor scorpion can spend 1 minute digging itself into the soil or other ground debris. It then waits for its tremorsense to detect prey. When a creature comes within range, it can erupt from the ground as a free action as part of a charge, allowing it to use its pounce ability. When dug in, the scorpion has improved cover granting it a +10 bonus on Stealth checks.
Poison (Ex) Sting—injury; save Fort DC 22; frequency 1/round for 6 rounds; effect 1d4 Str and 1d4 Dex; cure 1 save. The save DC is Constitution-based.
A giant emperor scorpion is an ambush predator, burying itself in soil or sand until prey approaches.
