"We could hear them in the night. That's when they came out, despite us not being able to see them. We started getting picked off one by one, until we fled the jungles. We went back in with a Wizard who claimed he could see the invisible. Said we were just fighting apes. Helped us fight them even, until something we couldn't see plucked him from the ground and crushed him like a grape 20 feet up in the air. We won't go back now. No matter what you or anyone else is willing to pay. You want whats in that ruin it's yours. I'll give you the map. But my help ends there."

In the Jungles of (insert name here) there is a legend that long ago a wizard was destroyed by his own creations, and that his former palace is now a rotting hulk, eaten by the jungle, and haunted by the remains of what he left behind. The truth is that there is a large fortress somewhere in the jungle, and it is haunted, not by apparitions, but by great apes that can walk unseen. When slain they appear, and are white, horribly malformed and misshapen gorilla like hominids. The apes are highly territorial, and omnivorous. They are smart enough to know that they are invisible, and are often quiet knowing that hearing and smell are the only ways most beings can find them. Adventurers will often blindly walk unawares into the entire colony of them. Spectral Apes are similar in size to Dire Apes, and do not appear to be capable of speech despite their higher intelligence.

Greater Invisibility (Su): This ability is constant, allowing the Spectral Ape to remain Invisible even while attacking. It works like the spell Greater Invisibility, and lasts as long as the Spectral Ape is alive (it becomes visible 1 minute after death). This ability is not subject to Invisibility Purge.

Improved Grab (Ex): If a Spectral Ape hits with it's Slam attack it can make a Grapple Check as a Free Action without provoking an Attack of Opportunity. If successful it may Constrict the next round.

Constrict (Ex): The Spectral Ape does 2d6+6 with a successful Grapple check.

Skills: Spectral Apes have a +8 Racial Bonus to Climb checks, and may always take 10 on a Climb check even if rushed or threatened.

Combat: Spectral Apes go straight for the Grapple. Lock up with the victim and rip him to shreds. Sometimes if there are groups they'll fling rocks, but generally they like to be up close and personal
