Assassin Bug, Giant

This giant version of the assassin bug is about 3 feet (1m) long, and lurks in bushes. Assassin bugs attack on sight (but not from the air), usually gaining surprise.
Their attacks are always at the torso, which they leap onto and grapple — treat as a slam attack. They have a 
piercing mouth. If the bug fails to penetrate by main force on its first attack, it will look for a crevice in the armor. If there are any such crevices, there is a 50% chance, each turn, that the bug will find one, making the victim essentially undefended. On the turn after its beak finds flesh, the assassin bug injects a digestive agent into its victim that succeeds automaticalls. It will then wait two seconds and begin to feed, drawing the digested tissue into its stomach (no extra damage).
When attacking it, the close combat rules apply. If it is successfully hit, it will remove the proboscis as it 
dodges. This does an additional 1d cutting damage (the proboscis is barbed). A contest of ST (the victim himself would be at -4) is needed to pull the beak out — it still does damage coming out. Once the beak is withdrawn, it will not automatically find the same hole in the armor, and must attack again.
