Master Spider
This is simply the oldest, wisest diamond spinner of the lair. As such, it has maximum hit points and the ability to communicate telepathically with all its offspring. The master spider guides the construction of the lair, a bubble-like maze, through mental commands.
Manotaur said:Forest Maze (Ex): A manotaur can create a natural labyrinth in its home forest. To do so, the manotaur must spend at least a month pounding out these paths with their hooves. This maze may cover up to one square mile. Any creature entering this natural maze must succeed on a DC 25 Survival check or become lost (see Getting Lost in the Dungeon Master\'s Guide).
