You're right. Nargacuga sleeps in trees where it is safer than on the ground but Barioth sleeps in an area not one bigger predator can reach (seemingly). I've only seen Lagombi as only other boss monster there.

The strategy of Barioth and Nargacuga are pretty similar though Narga likes to jump more around, but the hunting style is very different although both are ambush predators. Barioth needs to consider more to take down a prey as Nargacuga so this requires a bit more intelligent.

But Nargacuga has the pitfall trap jump and it also seems smarter IMO. I could see it (slightly) more than Barioth doing a feint and attack the surprised prey then. I still don't understand why feints of monsters aren't in the games yet. Would be pretty cool, wouldn't it? ^^
